First, set your digital multimeter to DC volts (20 volts). The current source and nano-voltmeter work together using internal techniques to synchronize their operation, eliminate thermal offsets, and improve measurement accuracy. When the device is placed within a magnetic field, the magnetic flux lines exert a force on the semiconductor material which deflects the charge carriers, electrons and holes, to either side of the semiconductor slab. The polarity of this transverse Hall voltage proved that it is in fact electrons that are physically moving in an electric current. In linear output Hall effect sensors, as the strength of the magnetic field increases the output signal from the amplifier will also increase until it begins to saturate by the limits imposed on it by the power supply. What controller is it specifically? To generate a potential difference across the device the magnetic flux lines must be perpendicular, (90o) to the flow of current and be of the correct polarity, generally a south pole. endobj Proceed to check the output of other wires. Then the movement of electrons through the semiconductor material is affected by the presence of an external magnetic field which is at right angles to it and this effect is greater in a flat rectangular shaped material.
