Solution
The correct option is C Temporary Magnet
A mixture of iron and nickel is magnetised by applying an external magnetic field. This converts the mixture into a temporary magnet for the time when the field has been applied. It is because the tiny magnets (domains) of iron and nickel get aligned along the external magnetic field. They become demagnetised when the external field is removed.
