In a generator, as the magnet spins, opposite poles of the magnet push the electrons in opposite directions. this back-and-forth movement of electrons is called what?
a) revolutions per minute
b) direct current
c) alternating current .
in contrast, the movement of electrons in one direction in a battery circuit is called what?
a)strength of current
b)direct current
c)alternating current .

Answer : (C) alternating current, (B). direct current

Explanation : In a generator, as the magnet spins, opposite poles of the magnet push the electrons in opposite directions. this back - and - forth movement of electrons is called alternating current.

1. When a conductor coil moves in a magnetic field the emf induced across the conductor that means current induced in the circuit. When a conductor coil moves under magnetic poles of opposite polarity then emf gets reversed.

2. In contrast, the movement of electrons in one direction in battery circuit is called direct current. Because it flows in one direction.
