Detailed explanation-1: -The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage. Was this answer helpful?

Detailed explanation-2: -The strength of magnetic field of an electromagnet depends on: Number of turns: The strength of magnetic increases on increasing the number of turns of the winding. Current: The strength of magnetic field increases on increasing the current through the solenoid.

Detailed explanation-3: -The answer is “all of these affect the strength of a magnet” The proximity to the object, the size of the object, the material of the object it is sticking to, and the temperature of the object all affect magnetic pull. Magnetism is the force by which objects are attracted to or repelled by other objects.

Detailed explanation-4: -There are two methods by which we can increase strength of magnetic field are: 1) By increasing the number of turns of wire in the coil. 2) By increasing the current flowing the coil.

Detailed explanation-5: -We can say that, the strength of the electromagnet is directly proportional to the number of turns in the coil. If you double the number of turns, you double the strength of the electromagnet.
