Answer 1

soft iron is used to make magnet because it aquare magnetic property in few hour

Answer 2

Pure iron or the soft iron is not used for making permanent magnets, because this type of iron cannot retain the magnetic power for a long time.

Permanent magnets can produce electricity with the help of a rotating coil,inside a electrical generator.

By the electromagnetism phenomenon we can easily convert any electrical conductor into a permanent magnet.

Devices like dc motor,pump, generator etc.,use permanently magnets as a vital component.
