Answer

Answer:

It is magnetized by the field of the solenoid and increases the magnetic field strength.

Brief Explanations:

In an electromagnet, the metal core (usually ferromagnetic) gets magnetized by the solenoid - generated magnetic field. This magnetization of the core enhances the overall magnetic field strength of the electromagnet.
