This vCalc equation computes the magnetomotive force (mmf) of a magnetic field generated by current.
This equation outputs units of Gilberts (Gb), which are equal to Amperes * turns.
Magnetomotive force (mmf) is is related to the magnetic flux in a magnetic circuit. Magnetomotive force is the phenomena that give rise to magnetic fields:
One way to express magnetomotive force is in the relationship of this equation:
`F = 0.4 pi *N*I`
where N is the number of turns in the coil and I is the electric current through the circuit.
