the material in a direction perpendicular to both the current and to the magnetic field [1]. This 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
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879. For clarity, the original effect is sometimes called the ordinary Hall
The first practical application (outside of laboratory experiments) was in the 1950s as a microwave power sensor. With the mass production of semiconductors, it became feasible to use the Hall effect in high volume products. MICRO. SWITCH Sensing and Control revolutionized the keyboard industry in 1968 by introducing
3 Nov 2012 ABSTRACT. In this paper Hall effect and its Application with electronically controlled BLDC motor is presented. . In section I and II the brief summary of Hall effect has been discussed. Later in section III the developed sensor based on the Hall effect has been discussed. This plays an important role in the
A. Introduction. The effect discovered by Hall in the year 1879 (I), and since then named after him, is one of the phenomena produced by the interaction between electric magnetic and thermal fields on one hand and moving charge carriers in a conducting medium on the other. Hall investigated Maxwell's theory about.
SUMMABY. After describing the discovery and early history of the Hall effect and the part it played in the development of theories of electronic conduction, the application of the Hall effect to semiconductor research is discussed. Experimental techniques for measuring the Hall coefficient and the procedures for interpreting.

The Hall effect was discovered by Dr. Edwin Hall in 1879 while he was a doctoral candidate at Johns Hopkins University in Baltimore. Hall was attempting to verify the theory of
Problem Description. If a current flows in a conductor (or semiconductor) and there is a magnetic field present that is per- pendicular to the current flow, then the combination of current and magnetic field will generate a voltage perpendicular to both. This phenomenon is called the Hall effect, discovered in 1879. The.
