magnetic field?</h3>
A magnetic field is a vector field that explains the magnetic influence on moving charges, currents, and magnetic materials. A moving charge in a magnetic field is subjected to a force that is perpendicular to both its own velocity and the magnetic field.
Magnetic fields cause electrically charged particles to move in a circular or helical pattern. The operation of electric motors is based on this force, which is exerted on electric currents in wires in a magnetic field. (See magnetism for further information on magnetic fields.)
Magnetic field is another term for it. GAUSS: A magnetic induction or magnetic flux density unit used to calculate magnetic field strength. (per square centimeter magnetic flux lines) GAUSSMETER: A device that measures the intensity of a magnetic field.
