TABLE 487. —Transverse Qalvanomagnetlo and Tbermomagnetlc EUects. 



Effects are considered positive when, the magnetic field being directed away from the observer, 

 and the primary current of heat or electricity directed from left to right, the upper edge of the 

 specimen has the higher potential or higher temperature. 



£= difference of potential produced; 7^:= difference of temperature produced; /= primary 

 lit 

 current; -j- = primary temperature gradient; ^= breadth, and Z? == thickness, of specimen: 



H= intensity of field. C. G. S. units.
