They are used in integrated circuits as Hall effect sensors. While certainly very useful in the automation world, even basic items such as a compass make large use of this scientific approach. Larger the current larger is the deflected electrons and hence we can observe the high potential difference between the plates. Of course, we know that the Hall Effect is used to measure magnetic fields and power overall. We will study Hall Effect Applications. This effect is also known as the Hall Effect. Hall Effect Sensor is based on Hall Effect Principle. A device to do so is called a Hall probe. On top of this, Hall Effect probes are safer, because the voltage never actually makes it directly to the sensor/probe. The sensor is used to accurately measure … On considering the above example of placing a magnetic bar right angle to the conductor we know that it experience Lorentz force. This principle can be regarded as an extension to Lorentz Force which is the force acting on the charge carriers (Electrons and Holes) passing through a magnetic field. For this purpose, so many sensors and transducers are available in market which have been using for different purposes. Thus, the sign of the Hall coefficient can be used to determine whether a given semiconductor is n or p-type. Server, Backplane and Power Supply Applications. To Determine Carrier Concentration: It is used to determine the electrons and holes concentration. Which can be represented by the following equation, t = average time between scattering events, M (dv/dt )= ( q ( E + v * B ) – m v) / t ——( 1 2 ), When a steady state occurs the parameter’ v ‘ will be neglected, If ’B’ is along z-coordinate we can obtain a set of ’ v ‘ equations, vx = ( qT Ex) / m + (qt BZ vy ) / m ———– ( 1 3 ), vy = (qT Ey ) / m – (qt BZ vx) / m ———— ( 1 4 ), Substituting in the above equations we can modify it as, Jx = ( σ/ ( 1 + (wc t)2)) ( Ex + wc t Ey ) ———– ( 1 7 ), J y = ( σ * ( Ey – wc t Ex ) / ( 1 + (wc t)2) ———- ( 1 8 ).
