lol this is the first time i read comments on your channel 😂 i always thought it'd be swarmed because you are like super famous in my view. Or at least you make super content. I cant believe I never thought to write something! I have been following you for years and i mean YEARS, surely more than 10 years. You are like an internal joke between me and my little brother, he was a kid when we found you. Every time some old relative tries to make an activity at like a family gathering we whisper something like "hes trying to pull off a Bruce Yeany". You are a true teacher, i can tell ;) you will not be forgotten. And when time comes, I hope you found someone to keep the channel alive, or someone finds you. Not for the money but for the science 🙏 Godspeed

Thank You GPalango, so pleased to hear that you've stuck with me for so long. Very funny that you're using my name as a commentary on others. My granddaughter 6 years old is starting a Homemade Science junior channel. While I intend to keep at for a while, I do hope that she will eventually take it on

a swivel ball joint would allow a more fluid chaotic path. i had a similar rig that i noticed the hook slipping, causing erratic jarring at times. but as always, an awesome demonstration!

That is a good idea, the first method I used was to have it attached with a small loop of string but as the magnets got near each other, it would cause the bar to bounce I would guess that eyelet to eyelet does restrict the movement some. One other option is to have magnets in both ends of the wooden dow, one end has the north side of the magnet facing outwards, and the opposite end of the stick has the south side facing outwards. That way you can reverse the charges very easily. At the top, a small eyelet is screwed into the support arm that the magnet will stick to..

@@YeanyScience i had explored the idea of countersinking the connections and dropping in ball bearing magnets, but this caused the arm to spin wildly, which while chaotic, was maybe a little "too much" chaos. 😂

Very cool

Your videos always have the best content!

what a cool way to teach about magnets!

This is a very interesting video, you were right to repost it! Hi from France!

thanks Bobby, I have several videos that included copyrighted music that I thought I had the license for, turns out I didn't so I am redoing them.

This is awesome

love your videos!!!

For anybody who doesn't know... why this is so cool is that even though it's a simple setup, and we understand all the physics and equations for it, we can't predict the path the pendulum will take.

It is too sensitive to even minutest of deviations in initial conditions and minutest of variations through the course of experiment, translating these minor difference to major effect on the outcome of its position and velocity overtime

Using string instead of a rigid pendulum could make things interesting, too.

Could you do a video on resonance? I saw a video recently of someone rubbing a singing bowl with water in it and the water was jumping all over the place and I thought that was cool.

Prof., could you maybe give us a link or a name for the specific violet laser that you're using? I understand (now) that the requirement is only that the wavelength of the light source needs to be shorter than the wavelength of the color of the paper. But I'm not seeing a big selection of laser diodes in that part of the spectrum. And I'd rather not use a UV laser if it's not necessary.

Do magnets do work. I get the Lorentz force but the equation doesn’t seem to match every day experience, example a car being lifted by a magnet at a scrap yard, or fridge magnet, or even this experiment where the inertia of the wooden dowel changes direction when it encounters changes in the magnet layout. Then it gets even worse when you factor in spin in physics.

You hinted at the answer to your question. Magnetic fields do not work on electric currents, but the spin-field interaction involves energy and work.
