How to use the faraday's law calculator
Compute induced emf from changing magnetic flux. Enter turns, change in flux, time in the fields above; the induced emf is computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- N — Turns
- dPhi — Change in flux (mWb)
- dt — Time (s)
Worked example
With turns = 100, change in flux = 5 mWb, time = 0.1 s, the calculator gives induced emf ≈ 5 V.
Frequently asked questions
What is the formula for the faraday's law calculation?
Induced EMF (V) = N × dPhi / 1000 / dt. Here N is turns, dPhi is change in flux (mWb), dt is time (s).
What inputs do I need for the faraday's law (induced emf) calculator?
You need turns, change in flux in mWb, time in s. 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 this 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 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.
