In physics, the magnetic moment or magnetic dipole moment is a measure of the strength of a magnetic source. The magnetic moment is defined as pole strength multiplied by the distance between the poles, μ = pd, and is considered to be a vector pointing along the axis of the magnet, from S to N.
The magnetic moment in a magnetic field is a measure of the magnetic flux set up by the gyration of an electric charge in a magnetic field. The moment is negative, indicating it is diamagnetic, and equal to the energy of rotation divided by the magnetic field.
In atomic and nuclear physics, the symbol m represents moment, measured in Bohr magnetons, associated with the intrinsic spin of the particle and with the orbital motion of the particle in a system. Also called magnetic dipole moment.
For a system of charges, the magnetic moment is determined by summing the individual contributions of each charge-mass-radius component.
Magnetic flux, is a measure of quantity of magnetism, taking account of the strength and the extent of a magnetic field. The flux through an element of area perpendicular to the direction of magnetic field is given by the product of the magnetic field density and the area element. More generally, magnetic flux is defined by a scalar product of the magnetic field density and the area element vector.

Magnetic moment is the ratio between the maximum torque exerted on a magnet, current-carrying coil or moving charge situated in a magnetic field and the strength of that field.
Expressed in webers, magnetic flux is the product of the average normal component of the magnetic intensity over a surface and the area of that surface.
