The numbers in the columns headed " magnetic properties" give the results for the highest magnetizing force used, 

 paper, it may be obtained by subtracting the magnetizing force (240) from the maximum induction and then dividing 

 netizing force " is the magnetizing force which had to be applied in order to leave no residual magnetization after 

 dissipated" was calculated from the formula: — Energy dissipated = coercive force X maximum induction -7- ir
