Ettingshausen effect

The Ettingshausen Effect (named for Albert von Ettingshausen) is a thermoelectric (or thermomagnetic) phenomenon that affects electric current in a conductor when a magnetic field is present.

The result of the phenomenon is that a potential difference is induced normal to both the direction of the magnetic field and the current.

Alternately, a temperature gradient is induced. This effect is quantified by the Ettingshausen coefficient |"P"|, which is defined to be

::$|P|=frac\{-1/(I\_YB\_Z)\}\{dT/dx\}$

where $dT/dx$ is the temperature gradient that results from the "y"-component $I\_Y$ of an electric flux and the "z"-component $B\_Z$ of a magnetic field.

The reverse process is known as the Nernst effect.
