ArchMageDiab Posted January 9, 2006 Share Posted January 9, 2006 Sorry if this seems like a stupid question but I do not know much about anything of science. What is electricity's reaction to a magnetic field and is it possible to projuct a magnetic field without having some surrounding apparatus? The reason for the question is an argument with a friend over the possibility of creation of an actual lightsaber like those used in star wars. He first suggested lasers which i said wouldnt work for several reasons then he suggested using a strong electric current contained within a strong magnetic field.

swansont Posted January 9, 2006 Share Posted January 9, 2006 The force on a charged particle is the cross product of its velocity and the direction of the field F = qv X B Making anything like the appropriate fields for confinement of a plasma will not be possible in a light-saber geometry.
