Answer:
No, it's not only when we use soft iron core.
Explanation:
A current carrying coil produces a magnetic field around it and behaves like a magnet.
But when we use soft iron core the strength of magnetic field increased as many times as actual value.
Due to the increase in strength of magnetic field Soft iron core is used in making commercial motor and electric generator.
In place of soft iron core we use other material like alnico, Nipermeg or steel etc.
