Magnetic Field Direction

Magnetic Field Direction

Prime purpose of this lecture is to present on Magnetic Field Direction. Direction of magnetic field at any point is defined as the direction of motion of a charged particle on which the magnetic field would not exert a force. Magnitude of the B-vector is proportional to the force acting on the moving charge, magnitude of the moving charge, the magnitude of its velocity, and the angle between v and the B-field. Unit is the Tesla or the Gauss (1 T = 10,000 G). The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire.
