 MAGNETIC SUSCEPTIBILITY. 



If 31 is the intensity of magnetization produced in a substance by a field strength 



then the 

 magnetic susceptibility H = 5l/I^. This is generally referred to the unit mass; italicized figures 

 refer to the unit volume. The susceptibility depends greatly upon the purity of the substance, es- 

 pecially its freedom from iron. The mass susceptibility of a solution containing p per cent by weight 

 of a water-free substance is, if Ho is the susceptibility of water, (p/ioo) H + (i — P/ioo) Hq.
