__Magnetomotive Force Formula:__

Magnetomotive force measures the force that generates a magnetic field in a magnetic circuit. It is analogous to electromotive force in an electrical circuit.

Magnetomotive force, mmF_{(A}_{⋅turns)} in ampere-turns is calculated by multiplying the current, I_{(A)} in amperes by the number of turns, N in the coil.

Magnetomotive force, mmF_{(A}_{⋅turns)} = I_{(A)} * N

mmF_{(A}_{⋅turns)} = magnetomotive force in ampere-turns, A-turns.

I_{(A)} = current in amperes, A.

N = number of turns in the coil, N.

__Magnetomotive Force Calculation:__

- A coil with 50 turns carries a current of 2 Amperes. Calculate the magnetomotive force.

Given: I_{(A) }= 2A, N = 50.

Magnetomotive force, mmF_{(A}_{⋅turns)} = I_{(A)} * N

mmF_{(A}_{⋅turns)} = 2 * 50

mmF_{(A}_{⋅turns)} = 100A-turns.

- Suppose we have a magnetomotive force of 150 A⋅turns and a current of 3 Amperes. Find the number of turns in the coil.

Given: I_{(A) }= 3A, mmF_{(A}_{⋅turns)} = 150A-turns.

Magnetomotive force, mmF_{(A}_{⋅turns)} = I_{(A)} * N

N = mmF_{(A}_{⋅turns) }/ I_{(A)}

N = 150 / 3

N = 50.
