Magnetic Floating Centerpiece: Gotta-See Video

//

Levitation is a hot topic, from maglev trains to quantum trapping. YouTube and DiscoveryNews are full of stories on levitating various objects. In this case, scientists are levitating a giant metal plate.

The video isn't actually about levitation, but instead about the creation of the electromagnet as a means of induction. Not only does the plate here float, but creates heat and light as well! The ideas are wonderfully simple, and seemingly magical. You gotta-see this. via The Verge
