Hall Effect Transducer
Definition: The hall effect element is a type of transducer used
for measuring the magnetic field by converting it into an emf.
The direct measurement of the magnetic field is not possible. Thus the Hall
Effect Transducer is used.
The transducer converts the magnetic field into an electric
quantity which is easily measured by the analogue and digital meters.
Principle of Hall Effect Transducer
The principle of hall effect transducer is that if the current carrying strip of
the conductor is placed in a transverse magnetic field, then the EMF
develops on the edge of the conductor.
The magnitude of the develop voltage depends on the density of flux, and
this property of a conductor is called the Hall effect.
The Hall effect element is mainly used for magnetic measurement and for
sensing the current.
The metal and the semiconductor has the property of hall effect .
Consider the hall effect element shown in the figure below. The current
supply through the lead 1 and 2 and the output is obtained from the strip 3
and 4. The lead 3 and 4 are at same potential when no field is applied
cross the strip.
