... When a changing magnetic flux is present, the integral is not zero but is dFB/dt. Thus, assigning electric potential to an induced electric field leads us to conclude that electric potential has no meaning for electric fields associated with induction. ...

Magnetic Forces on Charged Particles Right Hand Rule #3
... Instructions: Point your 4 fingers in the direction of the velocity (v). Curl your 4 fingers 90 degrees in the direction of the magnetic field (B). Point your thumb in the direction of the force (F). 2 of the variables will be given, so your hand will tell you the answer to the third variable. Remem ...

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.
