TABLE 593. — Transverse Galvanomagnetlc and Thermomagnetlc Effects 



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. 



E= difference of potential produced; 7"= difference of ' temperature produced; 1= primary
