what is the relationship between the strength of an electromagnet and the number of turns in the coil?

Question

a As the number of turns in the coil decreases the strength of the electromagnet increases
b The number of turns in the coil has no impact on the strength of the electromagnet
c as the number of turns in the coil increases the strength of the electromagnet increases

Answer 1

c as the number of turns in the coil increases the strength of the electromagnet increases
