The electrons are moving from left to right, so the magnetic force they experience pushes them to the bottom edge of the strip. This is most evident in a thin flat conductor as illustrated. Hall effect is defined as the production of a voltage difference across an electrical conductor which is transverse to an electric current and with respect to an applied magnetic field it is perpendicular to the current. If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers which tends to push them to one side of the conductor. When a magnetic field is applied to a current carrying conductor in a direction perpendicular to that of the flow of current, a potential difference or transverse electric field is created across a conductor. 1 – Photo of Edwin H. Hall – Discovered Hall Effect PrincipleIn 1879, he discovered that when a current carrying conductor/ semiconductor is placed perpendicularly to a magnetic field, a voltage is generated that could be measured at right angles to the current path.

The Hall effect is due to the nature of the current in a conductor. You must be logged in to read the answer. The field developed across the conductor is called Hall field and corresponding potential difference is called Hall voltage and its value is found to depend on the magnetic field strength, nature of the materials and applied current. However, when a magnetic field with a perpendicular component is applied, their paths between collisions are curved, thus moving charges accumulate on one face of the material. Determine the hall coefficient for a typical N-type Germanium semiconductor having thickness 0.8mm. The result is an asymmetric distribution of charge density across the Hall element, arising from a force that is perpendicular to both the 'line of sight' path and the applied magnetic field.
