Question

What can Lisa do to increase the strength of the electromagnet?


She can use a nail with weaker magnetic properties.

She can change the direction of the nail.

She can move the wire loops closer together.

She can reduce the number of wire loops.

Answer 1

Answer:

move the wire loops closer

Explanation:

because the closer t they are the more concentrated the energy is in that specific area

Answer 2

Lisa can move the wire loops closer together to increase the strength of the electromagnet. Option C is correct.

What is electromagnet?

An electromagnet is a magnet whose magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets.

A current flowing through the wire produces a magnetic field that is focused in the hole.

The strength of the electromagnet is increased by;

Adding further twists to the coil by wrapping it around a piece of iron and increasing the amount of electricity that flows through the coil.

Hence, option C is correct.
