# Formula Hall Effect Hall voltage    Hall constant    Electric current    Magnetic flux density    Thickness

## Hall voltage

Unit
This voltage is set between two ends of the Hall plate. The ends are perpendicular to the specified current direction.

## Hall constant

Unit
Hall constant is a material constant and depends on the material of the sample used. More precisely: It depends on the charge carrier density of the Hall plate and the polarity of the charge carriers.

## Electric current

Unit
Electric current is the number of charges per second that pass through the Hall sample (between two ends).

## Magnetic flux density

Unit
Magnetic flux density tells how strong the external magnetic field is, which is applied perpendicular to the Hall sample (and thus to the current direction).

## Thickness

Unit
Thickness of the sample in which the Hall effect is studied. This can be, for example, the thickness of a rectangular metal plate.
