Hall Effect

This interactive simulator explores Hall Effect in Electricity & Magnetism. U_H = R_H I B / t; R_H sign for e⁻ vs holes; B, I, n, t. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Electricity & Magnetism.

How it works

When a steady current crosses a conductor in a perpendicular magnetic field, Lorentz force deflects carriers until a transverse Hall field E_H balances it. The Hall voltage U_H is proportional to I and B and inversely proportional to thickness t and carrier density n. The sign of the Hall coefficient R_H distinguishes electron-like and hole-like conduction.

Key equations

U_H = R_H I B / t , R_H = −1/(n e) (e⁻) , R_H = +1/(n e) (holes)
|U_H| ∝ B I / (n t)
