Formula
Variables
- I — Current (A)
- B — Magnetic field (T)
- n — Charge carrier density (m⁻³)
- t — Plate thickness (mm)
Worked example
With current = 2 A, magnetic field = 0.5 T, charge carrier density = 8.5e28 m⁻³, plate thickness = 1 mm, the calculator gives hall voltage ≈ 0.07342952 µV.
Frequently asked questions
What is the hall effect voltage calculator used for?
Estimate the Hall voltage across a conductor carrying current in a magnetic field. It helps with questions such as “Hall voltage”, “Hall effect sensor”, “carrier density voltage”.
What is the formula for the hall effect voltage calculation?
Hall voltage (µV) = I × B / (n × QE × t / 1000) × 1e6. Here I is current (A), B is magnetic field (T), n is charge carrier density (m⁻³), t is plate thickness (mm).
What inputs do I need for the hall effect voltage calculator?
You need current in A, magnetic field in T, charge carrier density in m⁻³, plate thickness in mm. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the hall effect voltage calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the hall effect voltage result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
