When a piece of iron is rubbed with a magnet it acquires magnetism ' What kind of change is this and why ?
by

1 Answer

Answer :

When a piece of iron is rubbed by a magnet, it acquires magnetism ' is a physical or positional change. This is because when rubbed by a magnet, no other substance is formed from iron. Again , when a piece of magnetized iron is heated, it loses its magnetism and is converted into ordinary iron.
