Ratio of Charge to Mass (e/m) for the Electron
... Now turn the magnetic field back on, and bring one end of a bar magnet as close as you can to the electrons' path and observe the spiral path which the electrons now follow. Can you explain why the presence of the extra field distorts the electron's path? How will the Earth's field affect the motion ...

... called induction. A current can be produced in a loop when a magnet is moved into or out of the loop. There has to be a relative motion of the magnet and loop. Either or both can be moving. The greater the relative motion, the greater the current that is produced. If the north pole of a magnet is mo ...

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.
