The probe handle, being made of a non- ferrous material, has no disturbing effect on the field. A Hall probe contains an indium compound semiconductor crystal such as indium antimonidemounted on an aluminum backing plate, and encapsulated in the probe head.
The Hall effect is seen when a hallva is passed through a uniform magnetic field. Connecting leads from the crystal are brought down through the handle to the circuit box.

A Hall probe should be calibrated against a known value of magnetic field strength. Hall effect sensors have an advantage over inductive sensors in that, while inductive sensors respond to a changing magnetic field which induces current in a coil of wire and produces voltage at its output, Hall effect sensors can detect static non-changing magnetic fields.

Retrieved 2 September When the Hall probe is held so that the magnetic field lines are passing at right angles through the sensor of the probe, the meter gives a reading of the value of magnetic flux density B. This arrangement is commonly used to regulate the speed of disk drives. The result is what is seen as a charge separation, with a buildup of either positive or negative charges on the bottom or on the top of the plate.
As a consequence, one plane of the conductor will become negatively charged and the opposite side will become positively charged. A current is passed through the crystal which, when placed in a magnetic field has a ” Hall effect ” voltage developed across it. When a conductor is placed in a magnetic field perpendicular to the direction of the electrons, they will be deflected from a straight path.
They are used in brushless DC electric motors to detect the position of the permanent magnet.

The neutrality of this section is disputed. There are precision IC products available to handle these features. If the current is not changing, then the Hall voltage is a measure of the magnetic flux density.

The natural electron drift of the charge carriers causes the magnetic field to apply a Lorentz force the force exerted on a charged particle in an electromagnetic field to these charge carriers.

It may also provide and monitor the current to the Hall effect sensor itself.

Skin effect in conductor of rectangular cross section. As a result, the following materials are especially somda for Hall effect sensors:. Unfortunately, at frequency of Hz where the skin effect was evident the exciting current was to low, to find good agreement with theoretical prediction.
