This table shows the magnitude of electromagnetic force exerted by two electromagnets on each other as the distance between the two electromagnets is varied.

(See Attached Diagram)

The data on the table provide evidence for which of the following conclusions?

• The force between any two magnets is always constant, regardless of distance.

• As distance between electromagnets increases, the electromagnetic force also increases.

• The smaller the distance between two electromagnets, the greater the force.

• The force between two magnets depends only on the charge of the electromagnets.

How can the strength of an electromagnet increase?

• Remove the core, leaving only the coils of wire.

• Add more loops (coils) of wire around the core.

• Remove the battery.

• Remove loops (coils) of wire from around the core.
