Question

A magnet produces a magnetic field in the space around it, which ex-

erts a force on any other magnet placed in it. Field lines are used to

represent a magnetic field. A field line is the path along which a hypo-

thetical free north pole would tend to move. The direction of the mag-

netic field at a point is given by the direction that a north pole placed at

that point would take. Field lines are shown closer where the magnetic

field is greater.

a) What is a magnetic field line ? 1M

b) Can two magnetic field lines intersect ? Justify. 1M

c) Give two properties of magnetic field lines.​
