[dsc] Magnetic Gun Stops Teeny Bullets Mid-Air

March 12, 2008 -- It may sound like something out of an X-Men movie, but scientists have figured out how to stop a bullet, albeit a very tiny one, in mid-air.

Researchers at the University of Texas-Austin have built a so-called coilgun that works in reverse, stopping atom- and molecule-sized bullets in flight. The research could eventually help measure the mass of one of the most elusive and ubiquitous particles in the universe, the neutrino.

"What motivated this was weapons research," said Mark Raizen, a professor of physics at the University of Texas and one of the study's authors. "It's not often that weapons technology leads to basic research."

Coilguns are a standard feature of science fiction, but attempts by the military to make such a weapon practical have yet to succeed.

Conventional guns use chemical explosives to create hot gas, which propels lead bullets down a barrel.

A coilgun accelerates a magnetic projectile, usually iron-based, with a series of coiled wires that create a strong magnetic field. There is no physical contact between the projectile and the coils.

Only a few materials the size of real bullets are magnetic, but "when you look at individual atoms, just about everything is magnetic," said Raizen.

The coilgun consists of 64 hand-made units (about $25 each) and is powered by its own capacitor.

when can we expect these to be on shelfs for children to buy.

its a nice idea now if the bullets can be extracted from a solid metal bar (loaded in the gun) then well that would be just cool
