anyone enlighten me on the use of mgnets within circuits .I know the electric toothbrush employs these in the charging process. It's just that Ihave a few ideas
a) If you move a conductor across a magnetic field then a current is induced in the conductor (dynamo)
b) If you pass an electric current through a conductor that is in a magnetic field, then a force will be exerted on that conductor causing it to move. (motor)
