hall voltage calculator

Calculate Hall voltage from magnetic field, current, and carrier density using Vh (B ..I) (n q.t). Perfect for sensor and physics applications.

hall sensor formula

The equation to compute Hall voltage is V H = (B × I) / (n × q × t ) Enter the magnetic flux density and current and carrier density and conductor thickness.

Formula & Table Summary:

  • V_T = (k × T) / q
  • k = 1.380649 × 10⁻²³ J/K
  • q = 1.602176634 × 10⁻¹⁹ C

semiconductor hall voltage

To find the voltage V based upon the Hall effect, a Hall Voltage Calculator utilises the formula VH = (Bxi) / (nq). Suitable for magnetic sensing/semiconductor analysis. It is employed in the Hall effect sensors to measure the strength and direction of a magnetic field, current, position, and speed. Through the known parameters, the calculator has the capability of instantaneously giving the Hall voltage in volts or microvolts, hence can be of help to engineers and researcher,s and those who deal with magnetic detection systems as hobbyists in electronics.

Frequently Asked Questions - hall voltage calculator:

What is Hall voltage?

Hall voltage is the voltage generated across a conductor in a magnetic field due to the Hall effect.

How is Hall voltage calculated?

Use V_H = (B × I) / (n × q × t).

What units are used?

B in tesla, I in amperes, n in m⁻³, q in coulombs, t in meters, V_H in volts.

Why is Hall voltage important?

It’s used in magnetic field measurement, current sensing, and position detection.

Does material affect Hall voltage?

Yes, via charge carrier density (n) and type of carriers.

What are typical Hall voltage values?

Often in microvolts for metals, higher for semiconductors.

Can Hall voltage be negative?

Yes, depending on the type of charge carriers (electrons or holes).
