Professor Eric Laithwaite: Magnetic River 1975
Why people recommend it
A demonstration of alternating magnetic fields, including levitating conductive rings and a travelling wave, referenced when people ask about induction and levitation.
Watch for: Ring levitation at about 6:24; travelling wave demo near 8:45
In their words
I’m trying to make a device that can propel rings of conductive material upwards and make them hover, like the one seen in this video at 6:24, albeit on a smaller scale.
