Gap length:

Outer limb (core) length:

Outer limb (core) area:

Gap area:

Central limb length:

Calculate the magnetic reluctance:



The magnetic circuit can be calculated like an electric circuit, but with flux instead of current and with magneto-motive force instead of voltage (see the equivalent circuit above):
