... We can define a magnetic field B at some point in space in terms of the magnetic force FB that the field exerts on a charged particle moving with a velocity v, which we call the test object. For the time being, let us assume that no electric or gravitational fields are present at the location of the ...

... Two long, thin concentric hollow cylindrical shells are each free to rotate around the z-axis. A mechanical attachment (not shown) keeps them concentric. The two cylinders have the same length `, but different radii a and b. Each cylinder is an insulator, with a fixed charge per unit area, given by ...

... The Plage index is MWO’s Magnetic Plage Strength Index MPSI: For each magnetogram taken at the 150-Foot Solar Tower, a Magnetic Plage Strength Index (MPSI) value is calculated. To determine MPSI we sum the absolute values of the magnetic field strengths for all pixels where the absolute value of the ...

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.
