Question

State the purpose of soft iron core used in making an electromagnet ? ​

Answer 1

Answer:

Soft iron core is used to make electromagnets as it gains and losses magnetism quickly depending on existence of magnetic fields. The armature is also made of soft iron which can induce magnetism rapidly

Answer 2

Explanation:

Soft iron core is used to make electromagnets as it gains and losses magnetism quickly depending on existence of magnetic fields. The armature is also made of soft iron which can induce magnetism rapidly.

• It is because of following reasons. Soft iron core can easily gain magnetism when current flows around it if u will take steel in place of it.
• Steel will take much time to lose its magnetism after current flow is stopped.
• While soft iron will quickly lose its magnetism after the current flow stops.
