The simulation visualizes charge carriers diffusing along a temperature gradient inside a conductor and being deflected sideways by a perpendicular magnetic field, building up a measurable transverse Nernst voltage.
Adjust the temperature gradient and magnetic field strength sliders and toggle carrier type between electron-like and hole-like to see how the sign and magnitude of the transverse voltage respond.
Sliders for temperature gradient and magnetic field strength, plus a carrier-type toggle
Bismuth has one of the largest known Nernst coefficients of any elemental solid because its nearly equal densities of electrons and holes cancel in the Hall effect but add together in the Nernst effect.
