Write down the formula for the energy density of the magnetic field.
| September 30, 2021 | education
The energy of a uniform magnetic field is determined by the value of its induction, the magnetic properties of the medium and the volume of space occupied by the field:
W = B2V / 2µ0µ
where B is the modulus of the magnetic field induction; V is the volume of space occupied by the field; µ0 is the magnetic constant, µ0 = 4π ⋅ 10–7 H / m; µ is the magnetic constant.
In the International System of Units, the energy of a magnetic field is measured in joules (1 J).
