Answer to Question #325878 in Electricity and Magnetism for Joseph

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.
