If the distance between two magnets DECREASES, what happens to the magnetic force?

• The force will increase.

• The force will decrease.

• The force will remain the same.

• The force will create new magnetic poles.

If the strength of the magnetic poles INCREASES, what happens to the magnetic force between the magnets?

• The force will increase.

• The force will decrease.

• The force will remain the same.

• The force will create new poles.

According to Faraday's Law if you DECREASE the number of coils of wire, what will happen to the voltage?

• The voltage will increase.

• The voltage will decrease.

• The voltage will increase, then decrease.

• The voltage will remain the same.

According to Faraday's Law if you INCREASE the speed of the magnet moving through a coil of wires, what will happen to the voltage?

• The voltage will increase.

• The voltage will decrease.

How can you increase the strength of a magnetic field?

• decrease the number of electrons spinning in the same direction

• increase the number of electrons spinning in the same direction

• increase the number of protons spinning in the same direction

• increase the number of electrons not moving
