Question

By which of the following property of magnet, one can determine the direction?

• A. A magnet attracts magnetic materials towards itself
• B. A freely suspended bar magnet always aligns in the north-south direction
• C. A magnet with a single pole does not exist
• D. Any one of the above

Answer 1

The correct option is B A freely suspended bar magnet always aligns in the north-south direction

The north pole of the normal magnet points in the north direction of the earth. Thus by suspending a bar magnet freely, it aligns in the north-south direction.
