'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".
It's equation is: H = (IN) / l
where:
H = magnetic field strength (ampere per metre)
I = current flowing through coil (amperes)
N = number of turns in coil
l = length of magnetic circuit
