Garrettguy457 Posted July 23, 2008 Share Posted July 23, 2008 If I was to put a (-) charged plate on top of a lot of (-) gas particles, and then surronded the edge of the plate (extending down to the ground) with a magnetic field, wouldn't the plate float due to the like charges wanting to repele from each other?

insane_alien Posted July 23, 2008 Share Posted July 23, 2008 yes. although a negatively charged gas would not stay negatively charged for long as it would lose charge to its container. Link to comment Share on other sites More sharing options...
Garrettguy457 Posted July 23, 2008 Author Share Posted July 23, 2008 why would it lose its charge if its container has the same charge? Link to comment Share on other sites More sharing options...
insane_alien Posted July 23, 2008 Share Posted July 23, 2008 By depositing the charge on the container wall it reaches a lower energy level as like charges repel. the negative charge of the container would not repel the gas as the electric field strength inside a conductor is zero.
