Magnetic moment of magnet formula
WebEnergy in Magnetic Field = ½B.H =½μ0 (H + M).H = ½μ0 H2 +½M.H Energy of a magnetic moment m in magnetic flux energy to align one dipole = -m.B= -mzBz Energy density … WebA magnetic field is basically used to describe the distribution of magnetic force around a magnetic object. Magnetic fields are created or produced when the electric charge/current moves within the vicinity of the magnet. Here, the sub-atomic particle such as electrons with a negative charge moves around creating a magnetic field.
