Question

Assertion(A): Repulsion is the sure test for magnetism.
Reason(R): Attraction can occur between two unlike poles of a magnet and also between a magnet and a magnetic material.

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true, but R is not the correct explanation of A.
  
• C. A is true, but R is false.
• D. A is false, but R is true.

Answer 1

The correct option is A Both A and R are true and R is the correct explanation of A.

Repulsion is the sure test for magnetism because it occurs only when two like poles of a magnet exist while the attraction can occur between two unlike poles of magnets and also between a magnet and a magnetic material.
It means if there are two magnets they will attract each other and suppose if one material is a magnet and the other is iron then they will also attract each other so in that case, we cannot decide which is a magnet.
Therefore, both assertion and reason are true and reason is correct explanation of A.
