当10 000 Oe的横向磁场（$B$）反向时（“Umkehreffekt”），在78 K时铋单晶特定取向的塞贝克系数（$S$）改变40%。珀耳帖系数（II）也以相同的比例变化，但是给出较大塞贝克效应的场方向给出较小的珀耳帖效应。这是修正的开尔文关系式的验证，$\ensuremath{\Pi}（B）=TS（\ensuremath{-}B）$。
The Seebeck coefficient ($S$) for a particular orientation of a bismuth single crystal at 78\ifmmode^\circ\else\textdegree\fi{}K changes by by 40% when a transverse magnetic field ($B$) of 10 000 Oe is reversed in direction ("Umkehreffekt"). The Peltier coefficient (II) also changes by the same proportion, but the field direction which gives the larger Seebeck effect, gives the smaller Peltier effect. This is a verification of the modified Kelvin relation, $\ensuremath{\Pi}(B)=TS(\ensuremath{-}B)$.
