How is an electromagnet made? Name two factors on which the strength of the magnetic field of an electromagnet depends.

An electromagnet is an insulated copper wire which gets winded on a piece of soft iron bar.
It is U-shaped or a solenoid.
The magnetic field’s strength of the electromagnets depends on the number of turns of the wire around the coil and the current flowing through the wire.

Final Answer:
An electromagnet is made by winding an insulated copper wire on a piece of soft iron bar.
The strength depends on the number of turns of the wire and the current flowing through it.
