Problem
A small bar magnet is placed on a horizontal sheet of white paper and its magnetic field is traced with the help of a compass needle.
(i) Define (a) magnetic field and (b) magnetic field lines.
(ii) Draw a neat, labelled diagram showing at least six magnetic field lines around the bar magnet.
(iii) State any three characteristic properties of magnetic field lines that can be inferred from your diagram and briefly explain why no two magnetic field lines intersect each other.
