Chapter 29: Magnetic Fields
... Magnetism has been known as early as 800BC when people realized that certain stones could be used to attract bits of iron. Experiments using magnets have shown the following: 1) EVERY magnet has two “poles” which we refer to as north and south. These poles act in a way similar to electric charge, no ...

... Once a generator is producing electricity, it has a motor effect that tries to spin the loop in the opposite direction of the input. Once a motor has loops rotating, it has a generator effect that induces electricity in the opposite direction of the input. ...

... • The strength of a solenoid can be increased. – More loops or more current can create a stronger magnetic field. • electromagnet: a coil that has a soft iron core and that acts as a magnet when an electric current is in the coil – The magnetic field of the rod adds to the coil’s field. ...

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.
