H is the maximum value of the magnetizing force during each cycle. 



B is the maximum value of the flux-density or induction. 



fi is the value of the psrmeability corresponding tothe annexed values of B, 



and the hysteretic losses also corresponding to the values of H and B 



are given in ergs and watt-seconds.
