Question

An electric field on the surface of an object can be positive or negative, but you cannot have a surface that is only a magnetic north or south, why is this so?

Answer 1

Charge is one of the fundamental properties of the particle so a particle can have a negative, positive or neutral charge but this is not the case with magnetic field.

magnetic monopole is not possible. The main reason could lies in the fact that the magnetic property of any substance is due to the tiny magnet produced by the election spinning in that substance and because the electron creates a magnetic dipole so even if we break the magnet in tiny parts it's still have the magnetic dipole and we won't be able to create monopole
