Question
Which of the following statement is correct?
Options:
A .  Rubber is a magnetic material.
B .  The strength of a magnet near the centre is maximum.
C .  Bar magnets point towards North-South direction when suspended freely.
D .  Steel is not a magnetic material.
Answer: Option C
:
C
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 isnot a magnetic materialand steel is a magnetic material. The strength of a magnet is maximum at the ends.
