... magnetoquasistatic when the magnetic fields predominate. At first, electromagnetic waves are unimportant, yet the electric and magnetic fields are never static because of time varying sources, typically sinusoidal, because of geometry changing with time, or because media introduce their own dynamics ...

... anomalies in the ocean floor. The induction-based compass sense described here could enable an animal to travel long distances in the same direction by holding a constant ratio ω of A2ω z to Az . In addition, the animal needs simply change the phase of one component by 180 degrees to travel on the r ...

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.
