... (a) In this rule, the fingers point in the direction of v, with B coming out of your palm, so that you can curl your fingers in the direction of B. The direction of v x B, and the force on a positive charge, is the direction in which the thumb points. (b) In this rule, the vector v is in the directi ...

... 3. Another good demonstration is to put some iron filings in a jar with a small mouth. Place a cow magnet in a test tube and place it in the mouth of the jar. Tape the test tube to the mouth of the jar so that no iron filings can escape. Shake the iron filings so that they become aligned along the m ...

With both electric and magnetic fields, the strength of the field is strongest when close to its source and diminishes rapidly with distance from the source.

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.
