Electric current is the flow of electric charge.
... By DC, we mean direct current, which refers to a flow of charge that always flows in one direction. • A battery produces direct current in a circuit because the terminals of the battery always have the same sign of charge. • Electrons always move through the circuit from the negative terminal towa ...

Therefore the magnetic force cannot change a charged particle’s potential energy or electric potential. But electric fields can do work. This eq ...
