Question

(i) Two magnetic field lines do not intersect each other. Why?
(ii) How is a uniform magnetic field in a given region represented?
Draw a diagram in support of your answer.

Answer 1

(i). Magnetic field lines never intersect because at the point of intersection, the magnetic field would have two different directions, which is not possible.
(ii). A uniform magnetic field is represented by parallel and equally spaced straight lines. This indicates that the field strength and direction are the same at every point.
