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.
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].
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.
11. Move the Magnetic Field Sensor out of the magnet and move the Hall Effect Probe into the center of the magnet. 12. Click Preview and increase the Excitation Current to 50 mA and click Keep. Continue to increase the Excitation Current by steps of 50 mA up to 900 mA, clicking Keep for each current setting.
The Hall Effect. Abstract: The Hall effect was examined for a germanium crystal placed in a electromagnet. The hall coefficient was determined to be −0.0122 ±0.0009 m3C−1 . The charge carriers were determined to be electrons.
Introduction. 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 diference perpendicular to both the magnetic field and the electric current.
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
