The electromagnet is magnetized by the field of the solenoid and increases the magnetic field strength. Option C is correct.
What is electromagnet?
An electromagnet is a magnet whose magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets.
A coil of wire that carries an electric current is a solenoid. A solenoid is an electromagnet formed by a helical coil of wire. Which generates a magnetic field when an electric current is passed through the coil .
A solenoid is a form of coil that produces a magnetic field when the electric current is passed through it. A solenoid is created when a conductive wire is used to make a loop.
The electromagnet is magnetized by the field of the solenoid and increases the magnetic field strength.
Hence, option C is correct.
