There are many factors that influence the strength of an electromagnet. What could be done to make the electromagnet stronger?

To make an electromagnet stronger, more coils can be added to the solenoid, a greater amount of current can be sent through the solenoid, and a larger or more magnetic piece of metal could be used in the core.

The strength of an electromagnet can be increased or made stronger when the number of coils, radius of the coil and the current flowing in the electromagnet is increased.

The strength of an electromagnet corresponds to the strength of induced emf in the magnet.

The induced emf in the electromagnet is given as;

emf = NBIA

where;

N is the number of turns of the coil
A is the area of the coil = πr²
B is the magnetic field strength
I is the current flowing in the electromagnet

Thus, we can conclude that the strength of an electromagnet can be increased or made stronger when the number of coils, radius of the coil and the current flowing in the electromagnet is increased.
