effect is known as the Hall effect, and is the basis of many practical applications and devices such as magnetic field measurements, and position and motion detectors. With the measurements he made, Hall was able to determine for the first time the sign of charge carriers in a conductor.
The Hall Effect. Note: Please read the Radiation Safety Regulations at the back of this book. Objectives of the Experiment. The behaviour of the Hall voltage in a sample of doped germanium is studied in three different set-ups as follows: 1. 2. Constant magnetic field and temperature and varying control current.
In 1879, E. H. Hall observed that when a current-carrying conductor is placed in a transverse magnetic field, the Lorentz force on the moving charges produces a potential difference perpendicular to both the magnetic field and the electric current.
In 1879, E. H. Hall observed that when a current-carrying conductor is placed in a transverse magnetic eld, the Lorentz force on the moving charges produces a potential di erence perpendic-ular to both the magnetic eld and the electric current. This e ect is known as the Hall e ect [1].
experiment had sought to detect the magnetic effect of a static charge located on a moving conductor, namely rotating disc covered with gold leaf: the "Hall experiment" reversed that procedure by attempting to detect the influence of a magnetic field on an elec
