Abstract:

An formula is presented to calculate the magnetic field intensity by magnetic moment. Deriving separately from magnetic moment model of dipole and electric current loop, the same formula is derived, and the application condition and method of using the formula is discussed. Because the formula is simple, it is conducive to analyze and calculate the magnetic field around the magnetic moment. Moreover, a new way is given to get the magnetic moment by the magnetic field intensity.
