Solution

The correct option is C

Bar magnets point towards North-South direction when suspended freely.


Bar magnets point in the North-South direction when suspended freely. This is because the Earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle) to point always in a particular direction: North and South.
Materials which are attracted by a magnet are called magnetic materials. Hence, rubber is not a magnetic material and steel is a magnetic material. The strength of a magnet is maximum at the ends.
