My dad worked at University of Penn for 43 years. He worked on the cyclotron machine, he called it the atom smasher. I won first place in the science fair in high school with electromagnetism demonstrated with a copper coil wrapped around a bolt and a little compass. Thanks for your video it brought back good memories.

the summary of this video are: -as the current increases, the magnetic force increases. -based on the experiment done, we can conclude that forces come in pairs, and energy is conserved (when mechanical energy transform to electrical energy) lastly electrical behavior is not intuitive like the mechanical behavior. Lenz's law states that the current induced in a circuit due to a change or a motion in a magnetic field is so directed as to oppose the change in flux. group: anis afzan nur syafiqah bt lukman nurul batrisyia

Wow____so amazing technique to understand

It is a fact that power companies use the ability to change the phase relationship between voltage and current. Moving a magnet past a conductive loop induced a simultaneous voltage and current that reflect back the two components of electric power as the magnet moves. This puts the reaction in the conductor against the energy of movement in the magnet (the reflection is inverted.) changing the phase relationship of the magnet and loop would change the result, you don’t have to keep pounding your finger with a hammer after you hit it once. If the moving magnetic field and source charges of the magnet were inducing a charge in a capacitor, the opposite charge would attract the magnet’s charges first increasing the movement energy, then retard the movement as it moved away from the capacitor (a dance of first increasing the energy, then decreasing the energy; no absolute getting something with a direct cost (BTW, the energy generated depends on the rate of movement, so more energy is produced while approaching than is used to retard as it moves on.) then exchanges are not linear, amplification, getting something for nothing is the law of nature. Build a bifilar coil as Tesla patented it about 100 years ago and do the same experiment. The moving magnet will be accelerated through the loops, not retarded. Looks like a free lunch, but it’s using the capacitor to charge before the inductor (like it does in all LC circuits, and then force the inductor to do its thing as the magnet begins to discharge the cap as it moves away, creating a perfectly timed magnetic field that assists, not resists the moving magnet (nature produces both movement and electricity amplifying energy input to generate the electricity. It is a lie to say you must expend as much energy as you get to make electricity. Physics is not limited to unproven philosophical hypotheses, it is a science expressed by what can be done, even when the philosophical model fails to support reality.

IT IS VERY HELPFUL....THANKYOU!!!

This is a very helpful video with a nice selection of demonstrations. This said, there seems to be a small error at 4:20. The blue arrows indicating an eddy current are both being illustrated as being in the same direction.

The magnets in the tube reach an equilibrium speed, similar to terminal velocity.

Thanks to the Lenz effect, everyone can now easily and securely harness this negative force and add it to the total output possible from their system. Lens’s theory is the motoring effect in a generator and a generator effect in a motor. Lenz’s theory becomes a law when one is harnessing that negative output to add to the whole system. I suppose one has to own a bank to get something for nothing.

No current means no resistance. Voltage is present. The more current required the stronger the opposing force. That's why a generator bogs down under higher loads. We can design rings that produce more current with less heat and use thesetypes for next generation electric vehicles. Use larger copper current carrying conductors outside of turbines to lower resistance and prevent voltage drop. My vehicles will utilize flywheels and gearboxs at higher voltages to rotate turbines that will only be under load when heating or ac is needed or if the vehicle needs electric propulsion. The rest of the time the secondary battery will be charging. A depleted battery offers little resistance and accepts a charge with less force. More force will be required to top the battery off if you will.

We want this type of physics not in the in the written form or in imagination or to rut but we want it practical to get more benefit of it because physics is love ❤

I’ve been watching lots of videos on Lenz’ law and this is among the best. I remember in grammar school there was a man who demonstrated hovering a pizza pan above (what I suppose was) a large electro magnet. I remember that he used gloves to remove it before it became too hot. Is there the same phenomenon with the magnet and the spinning disc?

Ever since Elon Musk announced his intention to catch SpaceX’s Superheavy Booster, I’ve been wondering if Lenz’s Law would be one of means used towards achieving that goal.

❤❤❤💖❤❤❤🧡❤💖

That was a well done demo. Thanks. If I may ask. How is Lenzs' Law and the Lorentz force related? Is there a link that can demonstrate this?

Very nice

Hello and thank you for the video, it is very thorough yet simple and pleasant to follow and understand. :) I have a question about the 3 forces acting on the magnet falling down a tube: gravity and the two electromagnetic forces. If the two electromagnetic forces counteract each other, wouldn't gravity be the only force left acting on the magnet? Or did I get it wrong and the two electromagnetic forces counteract the force of gravity? Why do the two electromagnetic forces not cancel each other out? Sorry I am a new student to this. :) Thank you!

There is a clockwise induced conventional eddy current above the falling magnet and a counterclockwise induced conventional eddy current below the falling magnet. Each of these eddy currents have their own magnetic fields which as the professor said, pull up on the magnet from above and push up from below. So the falling magnet reaches a very low terminal velocity due to the two upward forces each countering gravity.

@4:30 he states there are three forces, two magnetic forces and gravity. The only problem is, gravity is not a force, it is an effect. The electromagnetic forces experienced by the magnet in the tube are detectable, gravity is not. Gravity is still not understood. No one has yet to explain why two objects with the same surface dimensions with vastly different weights fall at the same velocity.

I pretty certain that gravity is a force. Gravity is well understood in how it effects objects. Am I wrong to state that there relation is documented in Newtons law of universal gravitation. As for "why two objects with the same surface dimensions with vastly different weights fall at the same velocity." Has that been observed to happen?

00:09 🧲 Opposite poles of magnets attract, and moving a conductor through a magnetic field induces an electric current. 00:38 ⚖️ Lenz's Law states that the induced magnetism in a conductor opposes the change in magnetism that produced it. 01:19 🔄 When an aluminum ring falls between the poles of a horseshoe magnet, the induced current in the ring creates a magnetic field that opposes the magnet's field, slowing down the ring's fall. 02:14 🧪 Lenz's Law serves as a critical test for scientific theory, allowing for accurate predictions. 02:53 ✂️ A ring with a cut (breaking the closed path for current) falls unimpeded through the magnet, showing no effects from Lenz's Law. 03:32 🗂️ Stacking rings to form a tube and dropping a magnet through it shows each ring's current opposing the magnet's fall. 04:42 🔄 Energy is conserved when converting from mechanical to electrical energy; you can't get "something for nothing." 05:20 🚄 Lenz's Law is applied in magnetic levitation (Maglev) technology. 06:27 🌀 A spinning aluminum disk can lift a magnet off its surface due to the induced magnetism. 07:07 ⚙️ Electrical behaviors, though less intuitive than mechanical ones, still follow the same fundamental laws of physics. Made with HARPA AI

What my objection to the last one was that ,suppose,when the magnet is kept touching to the circular rotating disk,and suppose ,for an instant of time 'dt',the magnet comes in contact with and area 'dA' of the disk .So ,according to me if it comes in contact with an area dA,a current should be induced in that area ,which is so obvious.and ,as soon as that particular are moves a little away from the magnet,the magnet field lines passing through that area ,which has and induced current, decreases, so ,then accordingly, the leaving area dA should exert an attractive force towards the magnet and an area dA1,which has just approached the magnet,and due to which the number of field lines passing through it increases,should exert a repulsive force;and both of these forces should cancel each other everytime,eventually not letting the magnet float or move away from its position.. Isnt that true?

Magnetic induction

why does the force point upward on the ring?

Makes you wonder why people still use diesel engines in trains to move about. The answer is rather simple: The energy needed to move such a heavy thing is above huge which would result in so many magnets it would be ridiculous. Not to mention potentional interference with electronics and other metal parts laying around the track along the way or two trains meeting each other on opposite tracks (remember what happens when you put two magnets together). There is a magnetic train in use but it is a closed circuit for city usage only and this concept most likely won't expand any time soon. The reason is mainly cost (building, maintenance and running) and the efficiency over a regular railroad is not that big so it would compensate for the higher costs.

depends on how fast you push it, if its fast enough to induce eddy's currents it will slow down and the deceleration will be grater at the begining, and then it will leave the tube at the constant speed it decelerated to.

Please tell me if I'm understanding this correctly. When a non-magnetic conductive object meets two opposing magnetic fields, a current is produced. That current turns the non-magnetic object magnetic. So in the case of mag-lev technology when the non-magnetic object picks up speed against a magnet the current becomes greater which makes the magnetic effect greater. This repels the magnet and creates the levitating effect. Is that correct?

Just to ram home the idea that we do get more power than we personally inject, compare the ring test with the cut-out repeat; If you add the enegrgy you used to cut the ring, then see that the result got less power than the first test displayed, you see that more energy input can waste energy, if you do the wrong thing. If you get two guys jump from a height onto a giant bladder and a third person is catapulted into a lake from the other end of it, that person was just sitting there using no energy. The two just took a small step. They may have taken an e-bike up to the jump-off point. My point is the energy always comes from somewhere, but the individual does not have to provide much of it; this globe is packed with energy, and we just have to harness it. It's why men rode horses millennia ago.

No words😇😌

What if instead of aluminium ring we use iron ring which is basically a ferromagnetic in nature

So what about the inventors who have figured out a way to defeat lenses law and produce generators that have no resistance but still generate power? Lenses law only applies under certain conditions change the conditions and you can defeat lenses law. Which means your statement that you don’t get something for nothing is incorrect ,defeat lenses law and you can Generate electricity with very little input force at first then once it gets going no force is required.

@tdhanasekaran3536

Solar power generation depends on Photovoltaic effect and efficient design requires a thorough understanding of solid state and semiconductor physics. There are no physical moving parts and no need to know Lenz effect for a Photovoltaic scientist. They have 100 other problems to worry about for designing a high efficient and stable solar cells and panels. The research is still ongoing on all the fronts. The silicon based solar panels of today are only 10% efficient and has a lifespan of 25 years.

Excellent presentation and well put together video, thanks. Just a though experiment as I don't believe Lenz's law is at play here. It seems that the mass of the aluminum ring is changing. Could this not be explained by the dielectric planes of inertia combining to change the mass of the ring? In other words, the field medium through which the ring (or magnet as in the copper tube) is falling is being altered as coherency is being induced in the aluminum? Rather than magnetic, I see this as a dielectric phenomenon. The field mass of the magnet is combining with the ring as it falls. Cheers
