GEOLOGY

Detailed explanation-1: -When two magnets are brought close together, the magnetic field lines are perturbed, just as happens for electric field lines when two electric charges are brought together. Bringing two north poles together-or two south poles-will cause a repulsion, and the magnetic field lines will bend away from each other.

Detailed explanation-2: -Outside the magnets, the magnetic field lines point away from the north pole and toward the south pole. It is easy to understand the nature of the forces in Figures 7 and 8 with the rule that two north poles repulse each other and two south poles repulse each other, while unlike poles attract.

Detailed explanation-3: -If you have two magnets next to each other and their north poles are facing each other or their south poles are facing each other, you can see that the field lines move away from each other, so you feel a repelling force between the two magnets.

Detailed explanation-4: -If magnetic field lines intersect each other, then at the intersection point there will be two directions of the same field which is not possible. Hence the field lines do not cross or intersect each other. Was this answer helpful?
