Magnetic field strength in hysteresis?

Click For Summary
SUMMARY

The discussion centers on the units of magnetic field strength (H) in the context of magnetic hysteresis. Magnetic field strength is defined in amperes per meter (A/m), which is derived from the formula H = NI/L, where N represents the number of turns, I is the current in amperes, and L is the length in meters. The confusion arises from the interpretation of N, which is dimensionless and relates to the configuration of the coil rather than contributing additional dimensions to the unit of H.

Hi, I have been reading about magnetic hysteresis and all sources refer to magnetic field strength (H) as having the units (A/m). Why is it just amps/meter and not ampere-turns/metre as H = NI/L and not N/L? Is there another equation for H that I am unaware of?

Cheers.

two turns mean twice the H for a given current. N itself is dimensionless, determined by the configuration..
