Magnetic field strength in hysteresis?

  1. Oct 5, 2013 #1
    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?

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