Question

State whether the following statement is true or false.

The strength of an electromagnet depends on the amount of current.

• A. True
• B. False

Answer 1

The correct option is A True

Electromagnets:

1. The magnetic strength of an electromagnet can be increased by increasing the number of turns per unit length.
2. On increasing the current through the coil the strength can be increased.
3. And increasing the area of cross-section of the coil increases the strength of the electromagnet.

So, the given statement is true.
