Force on Moving Charges in a Magnetic Field
Magnets exert forces on other magnets even though they are separated by some distance. Usually the force on a magnet (or piece of magnetized matter) is pictured asthe interaction of that magnet with the magnetic field at its location (the field being generated by other magnets or currents). More fundamentally, theforce arises from the interaction of individual moving charges within a magnet with the local magnetic field. This force is written ,where is the force, is the individual charge (which...
