 CONVERSION OF UNITS OF MAGNETIC INTENSITY. 



The English unit of magnetic intensity is the force which acting for i second 

 on a unit of magnetism, associated with a mass of i grain, produces a 

 velocity of i foot per second. 



The C. G. S. unit of magnetic intensity is the dyne — the force which, acting on 

 one gramme for one second, generates a velocity of i centimetre per second. 



The dimensions of magnetic intensity are [M*/L^T].
