Question

True or false the number of coils and the number of batteries are factors that can affect the strength of an

Electromagnet

Answer 1

True.

The strength of an electromagnet depends on:

Increasing he strength of the current passing through the coil, the greater the current, the greater the strength;

Increasing the number of turns in the coils, the greater the number of turns, the greater the strength;

Whether the core is made up of a soft or hard magnetic material. Soft iron will magnetize more readily than steel. Therefore, using a soft core increase the strength of the electromagnet.
