Answer: Option B. -> North-South direction
:
B
A freely suspended magnet onthe Earth's surface always points in the North-South direction.This suggests that the Earth itself behaves like a magnet which causes a freely suspended magnetto point always innorth-south direction.

Answer: Option D. -> Like poles of magnets repel each other.
:
D
Every magnet has two poles. Magnets found in nature are called natural magnets. Artificial magnets are made by people in laboratory.Like poles ofmagnets repel each other and unlike polesattract each other.

Answer: Option C. -> Repulsion
:
C
Attraction can occur between unlike poles of two magnets as well as between a magnet and magnetic material. Therefore, thepieces that attracteach other couldbe both magnets, or amagnet anda magneticmaterial. In case of magnets,repulsion occurs only between like poles. Therefore, repulsionis the most reliable test for magnetism.

Answer: Option C. -> The Earth has a magnetic field and the pointer is magnetic.
:
C
The Earth has a substantial magnetic field. No matter where you stand on the Earth, you can hold a compass in your hand and it will always align itself along the Earth's magnetic field.

Answer: Option C. -> Compact disc
:
C
The magnetic property of a compact disc may be damaged when a powerful magnet is kept near it. Plastic, glass and wood are non-magnetic substances, hence they cannot be magnetised or demagnetised.

Answer: Option B. -> lodestone
:
B
Lodestone is a natural magnet and hencealigns in north-southdirection when freely suspended. In the old days, sailors used to find directions by freely suspending a piece of a lodestone. It works similar to a magnetic compass pointing towards north and south direction.

Answer: Option B. -> Cobalt, Nickel
:
B
Magnetic materials are the materials which are attracted by a magnet. Cobalt, nickel, iron and steel are attracted by magnet and hence, they are magnetic in nature. Aluminium, copper and lead are non magnetic in nature.

Answer: Option B. -> Cobalt, Nickel
:
Repulsion is a sure test for magnetism because to identify whether the rod or material is an iron rod, a magnet repulsion is the only way. This is because a magnet attracts an iron object and unlike poles repel each other.
