... The torque has a maximum value when the field is perpendicular to the normal to the plane of the loop The torque is zero when the field is parallel to the normal to the plane of the loop t I A B where A is perpendicular to the plane of the loop and has a magnitude equal to the area of the loop ...

... If the dipole field were the only field, the declination would vary in a systematic and predictable way over the Earth. For instance it would be zero along the meridians 111 E and 69 °W. The fact that the axis of the dipole field is only 11 degrees away from the axis of rotation is the reason that m ...

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.
