Question

Which variable does not increase the strength of an electromagne(1 point)
Responses

Increasing the number of coils
Increasing the number of coils

Adding batteries to the electromagnet
Adding batteries to the electromagnet

Increasing the thickness of the wire
Increasing the thickness of the wire

Increasing the distance between the coils
Increasing the distance between the coils

Answer 1

Increasing the distance between the coils.

Explanation: Strength increases with more turns and more current (adding batteries or using thicker wire can increase current), but spreading the coils farther apart reduces the magnetic field, so it does not increase strength.
