Japanese creative group Ugoita spices up traditional origami crane figures by adding electromagnets to their feet. The paper cranes stand on a board where the electric currents are applied to make them move and dance like the most awesome boy band I've ever seen.
Anyone who remembers high-school physics knows that a fluctuating magnetic field can induce an electrical current. That's the principle behind transcranial magnetic stimulation (TMS), where an electromagnet is held over the head and pulsed rapidly. Depending on the frequency of the pulses, this can either enhance or…
These paperclips, when placed on the floor of a japanese commuter train, stand up on their ends and dance whenever the train accelerates or brakes thanks electromagnetism.
I don't know what kind of school this kid goes to, but I doubt my shop teacher would have allowed me to build an electromagnetic coil gun that can send a round through a soda can.
For those who have a treasured item you want to display in style, the Levitron Revolution uses some sort of electromagnets—or anti-gravity voodoo magic—that levitates and slowly rotates your prized possession in space.
Gadget Lab got a hands-on demo with a prototype magnetic levitation haptic control unit at Carnegie Mellon University, where they experienced the artifical feel (via magnets) of 3d rabbits, hard surfaces and vinyl records. In addition to simulating the general shapes of objects, the technology can accurately reproduce…
It's a fake. Still neat, though.
