Magnetic field in airgap
Here is shown how to determine the airgap magnetic-field intensity and magnetic flux density. The field intensity Hg is approximately given by Hg=NI/2δ, and the flux density Bg = μ0Hg. Here μ0 is the permeability of free space.
In order to analyze the relationship between the current and the magnetic field, Ampere's integration theorem
∫H・dl=NI
is applied.
∫H・dl=NI is applied.
