Question

Which of the following statements is true?

• A. The north pole of a magnet will attract the north pole of another magnet.
• B. Artificial magnets can be made from non-magnetic materials as well.
• C. Lodestone is an artificial magnet.
• D. Isolated magnetic poles do not exist.

Answer 1

The correct option is D Isolated magnetic poles do not exist.

Isolated magnetic poles do not exist. On cutting a magnet into several pieces, each piece of a magnet behaves as an individual magnet, i.e., each piece will have its own set of poles. Poles of a magnet always exist in pairs.

Lodestone is a naturally occurring magnet. Artificial magnets cannot be made from non-magnetic materials. Magnets can always be made from magnetic materials only. Like poles of a magnet repel each other while unlike poles attract each other.
