Explanation:
This alone would be enough to produce magnetism, but electromagnets are improved with the addition of a “core.” This is a material that the wire is wrapped around, and if it's a magnetic material, its properties will contribute to the field produced by the coil of wire.

Answer: It is a soft magnetic material.
Explanation: As iron is a soft magnetic material, it is easily magnetised and demagnetised. This is why it is used as a core of an electromagnet.
