Elizabeth has two different electromagnets. Both electromagnets are connected to the same power source and are made of the same

materials for the wire and core. However, one of them produces a stronger magnetic field than the other one. What must be true about the electromagnets for this to be the case?
a. One of the electromagnets must have more turns of the wire than the other one
b. One of the electromagnets must be closer to the power source than the other
c. One of the electromagnets must be upside down and the other right side up
d. One of the electromagnets must have a core that is shaped differently from the other one

One of them produces a stronger magnetic field than the other one because one of the electromagnets must have more turns of the wire than the other one. Option A is correct.

<h3>What is electromagnet?</h3>

The magnetic field of an electromagnet is created by an electric current. Electromagnets are caused from conducting wire wriggled into a coil.

A magnetic field is created in the hole by a current passing through the wire.

The magnetic field production is increased by;

1) increasing the number of turns

2) increase the area of the loop

3) by moving the magnet faster

One of them produces a stronger magnetic field than the other one because one of the electromagnets must have more turns of the wire than the other one.

Hence, option A is correct.
