Magnetism and Gauss’ law

Magnetism and Gauss’ law: The net magnetic flux (∅B) through any closed surface is always zero.   This law states that the number of magnetic field lines living any closed surface is always equal to the number of magnetic field lines entering it. Let a closed surface S is held in a uniform magnetic field […]

The Electrostatic Analog

The Electrostatic Analog: The magnetic dipole moment of a bar magnet- M= m(2l), where,  m = strength of the pole and 2l = length of dipole. The magnetic dipole is analogous to an electric dipole consisting of two equal charges of opposite sign(+- q) separated by 2a. Electric dipole moment P=q(2a) The equation for magnetic
