Physics Demo -- Magnetic Motor

A toroid with three different wire windings is connected to 220 VAC 3-phase voltage. The voltage phase of each of the three windings lags 120 degrees behind the next, creating a changing induced magnetic field. The changing field causes metal objects to rotate when placed inside.

Motors using this principle are very common. In fact, power lines are often seen in sets of three because they are carrying three phases. For more information on 3-phase voltage, go here

Would it be possible to get a schematic of the toroid windings and specs / current draw of the egg of Columbus? I am a member of the Tesla Mail List and we have been trying to find info like this a long time. There is no need to do Tesla’s 2 phase setup. We like your three phase demo.

Thanks Much,

i found this cliping very nice and informative. thanks for the same. if possible show cliping, How linear drives are working on magnafield, which is widely used for laser beam head movement.

That is sweet! 200 years from now we will have figured out how to fly using the earth’s own gravity as a motor!
