The nce is perpendicular to the flow of the current as well as the magnetic field.
The Hall effect sensor usually consists of a small, rectangular section of semiconductor material such as gallium arsenide or indium arsenide. There is an conductor that carries current on one end and a voltage-measuring conductor at the back.
By applying a magnetic force parallel to the plane of the semiconductor, the electrons of the conductor that carry current are pushed to one direction due to the Lorentz force. This results in the accumulation of charges on that side and a decrease in the amount of charge that is to the other side. The electric field generated across the semiconductor creates a voltage differential between them which can be gauged by the voltage measuring conducting.
A Hall effect sensor produces an electrical voltage proportional to the strength and the flow of current through the conductor. When a sensor is able to measure its voltage output, the magnet’s strength and the it’s polarity can be assessed.
Current sensor Hall effects come with advantages , such as the non-contact sensor and high accuracy. This makes these sensors suitable for different sectors, such as industrial, automotive and medical.
