ANSWER:-
Permanent magnet strength depends upon the material used in its creation. The strength of an electromagnet can be adjusted by the amount of electric current allowed to flow into it. As a result, the same electromagnetcan be adjusted for different strength levels.
Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnetcan be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.
