Question

what type of core is used to make an electromagnet

Answer 1

The magnetic core is made up of ferromagnetic material such as iron

Answer 2

Answer:

A soft iron core is used to make an electromagnet.

Explanation:

• In an electromagnet, due to the flow of the current, a magnetic field is created.
• In loudspeakers, generators, motors, MRI machines, and hard disks, electromagnets are used.

The magnetic material should have a low retentivity and high susceptibility so that it can be used as a core of an electromagnet. If a material can be easily magnetized when a magnetic field is applied, then the material has a high susceptibility. If the material retains magnetism to a high extent, then the material has a high retentivity.

Low retentivity and high susceptibility are observed in the soft iron core. So, a soft iron core is used to make an electromagnet.
