MIT Physics Demo -- Levitating Magnet

Two flexible wires are suspended vertically. The wires are conected in series or parallel to a 12V storage battery. When the wires are connected in series and power is applied they will repel each other; when they are connected in parallel they weill attract one another.

This effect is due to the magnetic fields created by the charge flowing through the wires. When the wires are in parallel, the currents in each are going in the same direction and thus attract. In series the currents are going in opposite directions and repel.

wrong text in the side bar.

The text in the sidebar is from the "Forces on a Current-Carrying Wire" video.

Physics is really amazing!!

[smilinrk2003]

It is fantastically impressive and greatly encouraging to know that MIT Tech can post a video about eddy currents and yet write a description about magnetic fields induced by current carrying wires. Thank the heavens that they did use any names such as Faraday or Ampere to really impress us.

Guess they don't teach how to use the internet at MIT.

yes the internet show us the way

what we are waiting for?

Hahha.. wait r u serioius? Your the idiot. Why would MIT put on a FAKE demo?... BAKA.

[HoneycombAgent]

@KOTAmusic1992 What, don't you want magnets flying around the room?!

[KOTAmusic1992]

obviously fake. you can see the string idiot.

[AYOitseny]

thats was awesome.

Where are the flexible wires? where's the storage battery?
