PROPERTIES OF IRON AND STEEL. 



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

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

 neti/.ing force " is tlie maj^nctizing force which liad to be applied in order to leave no residual magnetization after 

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