GEOLOGY

Detailed explanation-1: -When the magnetic fields of two or more magnets overlap, the result is a combined field.

Detailed explanation-2: -When magnets are close together, with their fields overlapping, the fields combine to produce a resultant field which acts in one direction at any given point. The point X is called a neutral point. The forces due to both magnets cancel each other, i.e. there is no net force, at X.

Detailed explanation-3: -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-4: -There will be two directions of the field at the same point.

Detailed explanation-5: -No two magnetic field lines can intersect each other. If they do, there would be two directions of the field at that point which is not possible. Q. Can two electric field lines intersect each other?
