"I work at a school where cell phones are not aloud"Does that mean all the cell phones are on silent?

Please don't do that.Overlooking the idea of destroying someones property because they violated some sort of policy you would be exposing a child to to unknown levels of magnetism when you don't know what may be in their pockets or within their bodies. I would be very concerned you would cause an injury. Before you proceed, you should consult with your schools legal council and ask how they will defend you if you cause property damage or injury to a student?

where can i buy the magnet wire?
I work at a school where cell phones are not aloud, however students sneak them past the metal detectors and safety team regularly. Is it possible to create an electromagnet that safety could wave in front on students' pockets/shoes/bra/wherever they are hiding cell phones and iPods, that would be strong enough to ruin them? Since it is against school policy to have them and signs are everywhere saying that they are not allowed to bring them in the superintendent is not concerned about any liability issues for damages goes. If this is possible, how large do you believe I must make this electromagnet. It must be able to be moved up/down students bodies outside their clothes and be strong enough to penetrate through cloths and whatnot. I have enough room by the front doors to create it so large they would have to walk through it like the metal detector, but the smaller wand like one would be preferable. I'm assuming that folks with pacemakers should steer clear of a device like this as well correct...?Any input would be awesome, and help out my district tremendously!!!! Thanks!

Absolutely great method to reconditioning batteries http://bit.do/reconditioningbatteriesThank you Gregory! :)
Because conductivity (it is how much electricity the material allow to pass), altough aluminium is not-so-bad electricity conductor, copper is cheaper and better conductor.
Is there a reason why they always use copper for coils? I mean is there somthing special about it or is Aluminum just as good?
