... Frequently we wish to investigate the force (and subsequent motion) on an arbitrary charge due to a set of other known fixed charges. Although Coulomb’s law can be used it is generally more convenient to think of the fixed charges as producing a field The electric or E-field then exerts a force on a ...

... Thus, here for the case of a constant/uniform magnetic field B ( r ) = Bo zˆ we see that there is in fact a continuum of allowed magnetic vector potentials A′ ( r ) = A ( r ) + Ao = A ( r ) + ∇Φ m ( r ) that simultaneously satisfy B ( r ) = Bo zˆ = ∇ × A′ ( r ) and ∇i A′ ( r ) = 0 with the addition ...

During the acceleration periods, the engine is not running, so gasoline is not used and there is no emission. At higher speeds, the motor and engine work together so that the engine ...

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.
