What is the relationship between the strength of an

electromagnet and the number of turns in the coil?

As the number of turns in the coil increases, the strength

of the electromagnet increases.

The number of turns in the coil has no impact on the

strength of the electromagnet.

As the number of turns in the coil decreases, the

strength of the electromagnet increases.

As the number of turns in the coil increases, the strength of the electromagnet increases.

Explanation:

When current flows through a coil the coil behaves as an electromagnet. The strength of electromagnet depend the amount of current, no of turns of coil and the core of coil.

B=μ₀ N I

μ₀ = permeability of the core

N = Number of turns of the coil

I = Current flowing through the coil

Increasing the current and number of coils increase the strength of electromagnet.
