Final answer:

Increasing the number of coils in a solenoid results in an increase in the strength of the electromagnet due to the induced emf being proportional to the square of the number of coils.

Explanation:

The relationship between the number of coils in a solenoid and the induced emf:

Increasing the number of coils in a solenoid increases the strength of the electromagnet. This is because the induced emf is proportional to the square of the number of coils in a solenoid.
