So berechnen Sie Faradays Law

learn.whatIsHeading

Faraday's law relates changing magnetic flux to induced electromotive force. It's the principle behind transformers, generators, and induction cooktops.

Formel

The calculator applies EMF = -dΦ/dt

EMF: -dΦ/dt — -dΦ/dt

Schritt-für-Schritt-Anleitung

1Enter magnetic flux change and time interval
2The calculator applies EMF = -dΦ/dt
3Results show induced voltage magnitude

Gelöste Beispiele

Eingabe

ΔΦ = 0.1 Wb, Δt = 0.001 s

Ergebnis

EMF = 100 V

Rapid flux change induces high voltage

Häufige Fehler vermeiden

✕Ignoring the rate of change; steady flux produces no EMF
✕Forgetting that area and angle both affect flux

Häufig gestellte Fragen

What does the negative sign mean?

It represents Lenz's law: induced current opposes the change causing it.

How do transformers use Faraday's law?

Changing current in primary coil creates changing magnetic field, inducing voltage in secondary coil.
