20-4 Motional emf
... In each of the loops in Figure 20.17, the induced emf is associated with only one side of the rectangle, the side completely in the field, aligned perpendicular to the loop’s velocity. Let’s address this emf from another perspective. EXPLORATION 20.4 – A metal rod moving through a magnetic field As ...

12.2 Oersted`s Discovery
... Oersted’s Experiment Before Oersted, many physicists had hypothesized that magnetic fields could be created by an electric current in a wire. Oersted hypothesized that the current would produce a magnetic field that radiated away from the wire. He tested his hypothesis with a compass held near a con ...

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.
