A. It is a coefficient that represents the disaccommodation, when the initial permeability is exponentially changed with respect to time, is calculated with the following formula, and is normally represented by units of 10–6.

 

Here:

  • μ1 : Initial permeability noted at t1 seconds after complete demagnetization
  • μ2 : Initial permeability noted at t2 seconds after complete demagnetization
