Hysteresis Coefficent Units

  1. Aug 11, 2016 #1
    I'm working with hysteresis losses in transformers at the moment, and I was wanting to know if there are units for the coefficient.

    Normally, I'd just rearrange the equation for units, below,

    so it would have units

    However, given the power of 1.6, I'm not sure it still works like this. Does anyone know the units for it?

    Hysteresis loss [for instance] formula :

    Ph=lh*B^n*f Watt/m^3 where:

    B in Tesla=Wb/m^2

    n=1.6 to 1.8

    lh is a property of material about 500 for 4% silicon steel or 3000 for cast iron.

    f=50 or 60 Hz

    See [for instance]:
