Question

List two ways of increasing the strength of an electromagnet if the material of the electromagnet is fixed.

Answer 1

Two ways of increasing the strength of an electromagnet if the material of the electromagnet is fixed:

1. By increasing the amount of current flowing in the solenoid, the strength of an electromagnet can be increased.
2. By increasing the number of turns in the solenoid, the strength of an electromagnet can be increased.
