GEOLOGY

Detailed explanation-1: -Magnetic field increases as we go away from a magnet.

Detailed explanation-2: -As we increase the current (amount of charge in motion) the field increases proportionally. As we move further away from the wire, the field we see drops off proportionally with the distance. This is described by Ampere’s law.

Detailed explanation-3: -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-4: -How close or far away an object is really counts in magnetism. The closer you stand to a magnet, the stronger the magnetic field will be. The farther away you are from a magnet, the weaker the magnetic field becomes. A magnetic field never ends.

Detailed explanation-5: -The magnetic field magnitude is proportional to the density of the lines. The closer together the field lines, the stronger the magnetic field. The more spread out they are, the weaker the magnetic field.
