Question
Science Question on Magnetic Effects of Current and Magnetism
(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
(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.
