Answers

Answered by foruhh8888

Answer:

options a is correct

Explanation:

Repulsion is the surest test of magnetism. Because a magnet can attract a magnet as well as another magnetic substance but it can only repel a magnet, not any magnetic substance. Hence, if one end of iron bar is repelled by the north pole of a bar magnet then it's surely a magnet.
