Detailed explanation-1: -When considering the repelling force between two magnets, you must consider the distance between them. The farther two magnets are apart from each other, the weaker the repulsion force will be.

Detailed explanation-2: -Magnetic Fields Varying as an Inverse Cube For both monopoles and dipoles, the field strength decreases as the distance from the source increases., often called the inverse square law.

Detailed explanation-3: -If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. If the distance between two magnets is halved the magnetic force between them will increase to four times the initial value.

Detailed explanation-4: -The magnitude of the magnetic force is inversely proportional to the distance between two magnets. So, if the distance is decreased, the mutual magnetic force between them will increase.

Detailed explanation-5: -Magnetic field due to a magnet decreases with increase in distance and hence, magnetic force between two magnets decreases with increase in distance.
