The Nernst effect is a phenomenon in which a magnetic field applied perpendicular to a current-carrying material induces a voltage gradient in the direction perpendicular to both the current and the magnetic field. This effect is observed in conductors with a net charge carrier density, such as metals, semiconductors, and electrolytes.
The Nernst effect can be explained and predicted by statistical physics, specifically the theory of transport phenomena. This theory models the behavior of charge carriers in materials and predicts the presence of a voltage gradient when a magnetic field is applied.
The Nernst coefficient is a measure of the strength of the Nernst effect in a material. It is defined as the ratio of the induced voltage gradient to the applied magnetic field. The coefficient can be calculated experimentally by measuring the voltage gradient and the magnetic field strength, or theoretically by using the Onsager relations, which relate the transport coefficients of a material.
The Nernst effect has several practical applications, such as in thermoelectric devices, magnetic field sensors, and spintronics. The effect can also be used to measure the strength of magnetic fields and to study the properties of materials, such as the charge carrier density and mobility.
Both the Nernst effect and the Hall effect are phenomena that occur in the presence of a magnetic field, but they differ in their underlying mechanisms. The Hall effect is caused by the Lorentz force on moving charges, while the Nernst effect is a result of the interactions between charge carriers and a magnetic field. Additionally, the Hall effect produces a transverse voltage, while the Nernst effect produces a voltage gradient in the direction perpendicular to the current and magnetic field.
