There is another quite different field that exerts forces on electric charges only if they are moving. Equally strange, the strength of the exerted force depends upon the direction of the charge's motion. This peculiar behavior reveals the presence of a magnetic field .These keywords were added...
and magnetism is described byFaraday's Law of Induction, which is the basis for electromagnets, electric motors and generators. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire. When that wire is formed into a loop, the...

The magnetic force is the force between magnetic poles, such as the north and south pole. In fact, the Earth is like a large bar magnet, with a north and a south pole. Many animals use the Earth's magnetic field to navigate during their migrations. ...

One can then easily control and tune the interactions between the grains of the packing (using an external magnetic field), in contrast for instance to the influence of the particles shape and roughness on the frictional properties15,16, or to the cohesive forces induced by capillary bridges in...
