A temporary magnet should be made from

A. Copper
B. Tin
C. Iron
D. None of these

Check Answer

The correct answer is C) Iron.

A temporary magnet is a magnet that can be magnetized and demagnetized easily. It is usually made from a magnetic material such as iron, which can be magnetized by placing it in a magnetic field. When the magnetic field is removed, the iron loses its magnetism and becomes demagnetized. Other materials such as copper and tin are not magnetic and cannot be used to make temporary magnets.
