you havn't told us whither the bar and the wire are insulated from each other not have you specified whither the electricity is passed through the bar or the wire
furthermore  to be pedanic. it is not clear whither you are making a statement or asking a question.

infact im just greatful to have a half decent discussion on the matter

though it

then the bar shows a magnetic charge as if the electricity is still there for a good while

is this effect soley , residual electricity , or mirrored electricity or both

thanks!

a charge passes through it if the wire around the bar is moved through a magnetic field.

also, if you pass a charge through a wire, it creates a magnetic field.

it does just create a charge by wrapping itself around metal...and the metal has to be ferrous in nature in order to hold a field.

You'll get this kind of misunderstanding anytime you discuss higher concepts.  People feel content to view the world through the constructs they've been given.  When you discuss things beyond the comprehension of this construct, they resort to belaboring the basic understanding that they feel comfortable with. 

It is much easier to be condescending and reply "magnets either repel or attract...we learned that in 8th grade" than it is to go to look deeper into the root of magnetic action by asking "fucking magnets, how do they work?"


You can tell them that things like "magnets do no work" (so how can they move things?), but they will continue to resort to what's comfortable--the rudimentary explanation that was the mental sedation of their youth.
