Think you'll find the charging in toothbrushes is done by induction loops, not magnets.

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)
