Presenting the counter EMF that is produced in the coil as a manifestation of Lenz's Law will help. Here's the fine details of the reason it take time for full current to flow in the inductor: 1) battery connected to circuit, current starts to flow, magnetic field therefore begins to build up around the wire and the inductor 2) the building-up magnetic field actually causes electromagnetic induction **onto the coil** - the changing magnetic field induces a voltage in the very same wire (the coil) that is creating the initial magnetic field 3) the voltage induced by induction onto the coil by the initial magnetic field IS OPPOSITE the voltage in the circuit and creates current flow/magnetic field IN THE OPPOSITE DIRECTION of the initial magnetic field - *_this is Lenz's Law_* 4) an equilibrium is finally reached - the initial current caused by the battery reaches a maximum. That means the initial magnetic field STOPS CHANGING (stops increasing). Because the initial magnetic field stops changing, the back EMF (Lenz's Law - back or reverse electromotive force, aka reversed voltage) goes away This subtle point is skipped over in many electronics courses. I found what is generally taught is "it takes five (5) L/R time constants for the magnetic field to build up" with no explanation as to 'why.' The 'why' is the SELF-INDUCTION of the primary magnetic field right back into the coil, in the OPPOSITE DIRECTION. The five L/R time constants accurately accounts for the time it takes for the self-induction to stop fighting against the initial current and magnetic field from the battery. Having taught the subject, many students are surprised about the self-induction as the cause for the delay in reaching max current through the inductor. I explain it this way when that happens: 1) "Remember Faraday's law of induction - where a changing magnetic field induces an EMF in a conductor?" (students: 'yes') 2) "Remember Lenz's Law, which completed Faraday's law of electromagnetic induction by putting a negative sign on the induced voltage?" ('yes') 3) "When the battery is first connected to the circuit and current begins to flow and the initial magnetic field begins to build up in the inductor, do we have a changing magnetic field?" ('yes') 4) "Is there a conductor near the changing magnetic field?" ('yes') "Is the COIL the conductor next to the changing magnetic field?" ('yes') 5) "What is the direction of induced EMF (voltage) that occurs in the coil by the changing magnetic field? Hint: Lenz's Law" ('it opposes the initial current from the battery') 6) "So the self-induction onto the coil opposes the initial magnetic field?" ('yes') Some students will say "but shouldn't the coil KNOW that it should not allow its growing magnetic field to trigger Faraday's law of induction ON ITSELF?" to which I say "the wire is not sentient, it does not know. You can say the WIRE IS SELF-DEFEATING if you want" I then point out "if the self induction back onto the coil was NOT in the opposite direction of the initial magnetic field - but was instead in the SAME DIRECTION - the magnetic field would keep growing and growing, which Nature would never allow"

Thank you so much for this, this is really helping me through my electrical fundamentals for my diesel AAS! But I did have a question about the current, when you find all the currents for the parallel circuits, the resistors 1, 6, 7, and 12 world be 1.5 amps, correct? Because that current meets up after it passes through the parallel circuit?
@DorianMcIntire3 жыл бұрын
Yes. The current leaving and entering the power supply must always be the same. If the current has only one path it will be the total current (1.5 A) and if the current has more than one path it will split up and the current entering a set of parallel resistors must equal 1.5 A and the same current will leave that set of parallel resistors. Also the highest currents will always flow in the lowest resistors.

@DorianMcIntire3 жыл бұрын
If you use parts from a microwave oven transformer and use the primary coil (about 14 gauge wire) you should have no problem. There are many reasons an electromagnet may not work as well as the one in the video and I explained the reasons in the comments. The most likely issues are using a higher voltage European microwave and using the secondary coil (high voltage) instead of the primary coil (low voltage - 120 Volt).

@DorianMcIntire3 жыл бұрын
Potential energy is energy possessed by an object due to a force applied to the object (e.g. gravity, spring, etc). Kinetic energy is energy possessed by an object due to it's speed (e.g. high speed car, bullet, etc). A bullet posses very little energy due to it's weight (force of gravity) but it posses a huge amount of energy due to its speed while moving). I suggest that you Google the terms. I electronics the moving electrons posses energy since moving electrons create a magnetic field and this magnetic field posses energy.
