Mind Controls: Magnetic Relief For Depression

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… » 4/11/11 5:20pm 4/11/11 5:20pm

Japan's Electromagnetic Trains Cause Paperclips to Dance

Woodshop Class: Where Bolt-Action, Electromagnetic Coil Guns Are Made

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. » 6/18/09 12:00am 6/18/09 12:00am

Levitron Revolution Makes Your Junk Look Awesome While Suspended in…

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. » 6/11/09 9:00pm 6/11/09 9:00pm

Maglev Haptic Control Technology Could be Used for Microsurgery, Robot…

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… » 3/05/08 6:15pm 3/05/08 6:15pm
