WebElectrical resistivity is a basic measure of how well a material conducts electrical current. When a magnetic field is applied non-collinearly to the current direction, the Lorentz force bends the trajectory of charge carriers and leads to a potential difference. This is known as the Hall effect, named after Edwin Hall who discovered it in 1879.
