Answer 1

C. Increase the voltage of the battery

Step-by-step explanation:

To make the magnet stronger, we need to increase the current, so by ohm's law, we get:

`V=IR`

Where V is the voltage, I is current, and R is the resistance. So, to increase current, we can increase the voltage.

Therefore, the magnet will be stronger if we increase the voltage of the battery.
