in a magnetic field, pressure exerted on a conducting fluid
where
B is the magnetic flux density
μ0 is the magnetic constant
Note 1 to entry: The total pressure on a given flow of conducting fluid, which is the sum of the mechanical pressure, the magnetic pressure and the hydrostatic pressure, is a constant for this flow of conducting fluid. Note 2 to entry: The coherent SI unit of magnetic pressure is newton per square metre, N/m2.
