GEOLOGY

Detailed explanation-1: -The magnetic field is the strongest at the poles of a magnet, so the lines are closer to each other at poles.

Detailed explanation-2: -Answer and Explanation: The electric field is the gradient of the potential. If the equipotential lines are closer together, the potential changes by the same amount over a shorter distance. Consequently, the electric field is stronger in this case.

Detailed explanation-3: -The magnitude of the electric field is stronger (or greater) where the electric field lines are closer together and the electric field is weaker (or smaller) where the electric field lines are farther apart.

Detailed explanation-4: -Lines are closer together where the field is stronger. Larger charges have more field lines beginning or ending on them. Electric Field lines never cross (since E must point in a definite direction unless it is zero).

Detailed explanation-5: -Poles that are the same (“like poles”) will always repel each other. It is the magnetic force that attracts and repels. The force is stronger when magnetic objects are closer together. The force weakens when magnetic objects are farther apart.
