This looks to be using Two of the basic experiments I've shared more than 5 years ago.

First, one copper wire with DC current is fasten to a Neo magnet and another wire is used to make contact to magnet (on correct pole) will make an on off oscillating switch due to the magnetic field created around the wire when it first contacts the magnet will momentary repel the wire causing repeating on off oscillation switch.

Second, a coil place between two opposing  magnets will cause a linear movement to the coil or in this case the magnets will move in the coil.

I think it's really only using the second effect, which is the Mostly Magnet Motor principal.

It's interesting to see it this way.

Thanks for sharing it Chet

Absolutely Amazing Genius Creativity.

How about connecting a Voltmeter to the 2 ends of the Coil
to see how much voltage is being generated during operation.

Why not build one for yourself and see? Surely you have three dollars to spend, and a DMM to connect.

I think gotoluc has explained it very well. I can't quite figure out, though, whether there will be a measurable voltage between the ends of the coil or not. The magnets/battery combo are producing current that is going through the small portion of the coil that it is in contact with at any given time, and this current through that bit of coil is producing the field which then moves the magnets, and the battery along with them just as Luc has explained. The moving magnets will generate an EMF in the coil as well but I don't know if this can be detected at the far ends of the rest of the coil or not.

I don't have any bare copper wire, nor do I have three dollars to spare, so someone else is going to have to do the experiment and report the result.

The title of the thread should be changed, though, to something like "TA's Plagiarized $3.00 magnet-battery copper-coil "train"" though, since it's not his video or idea, he just reposted someone else's video on his channel without giving credit to the originator.

  Koala,
  If you scrutinise the last seconds there's a footnote with something on it.
