What causes the electrons to move in the “electromagnetic induction” animation?
a. current
c. changes in magnetic field
b. voltage
d. kinetic energy

The correct answer is "Changes in magnetic field".

Explanation:

Electromagnetic induction: It is the production of the electromotive force or the production of the voltage across the conductor by changing the magnetic field.

The induced voltage can be affected by changing the magnetic field. The voltage can be induced by moving the conductor in the magnetic field or by changing the magnetic field around the stationary conductor.

In electromagnetic induction, the change in the magnetic field causes the electrons to move. The rate flow of the electrons constitutes the current in the conductor. The current will be induced in it.

Therefore, the correct option is (c).
