The Ettinghausen Effect is a thermoelectric (or thermomagnetic) phenomenon that affects electric current in a conductor when a magnetic field is present.
Additional recommended knowledge
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 Ettinghausen coefficient |P|, which is defined to be
where dT / dx is the temperature gradient that results from the y-component IY of an electric flux and the z-component BZ of a magnetic field.
The reverse process is known as the Nernst effect.
