... As a result the centers of the positve and negative charges move in opposite directions and do not coincide. Thus a non-zero electric dipole moment p appears. This is known as "induced" electric dipole moment and the molecule is said to be "polarized". When the electric field is removed p disappears ...

... For an infinite horizontal plane the only reasonable direction for the electric field E is vertical. Electric field can be determined by integrating over the charge distribution (try it yourself). It is not too surprising that the field is the same at all distances above the plane. ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
