... In ferromagnetic substances like iron and nickel, their atoms have a number of unpaired electrons whose magnetic fields are NOT cancelled by opposing motions. Atoms in ferromagnetic substances cooperate with 1015 – 1020 nearby atoms to create small microscopic regions (10-6 m) called domains in whic ...

magnetic field effects on quality of human life
... Electromagnetic fields are detected only in very strong direct exposure situation by the human body; this situation arises only in a professional environment or carried out on 21 volunteers during experimental studies. The instantaneous effects are well-known in the international scientific communit ...

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.
