Faraday's law relates changing magnetic flux to induced electromotive force. It's the principle behind transformers, generators, and induction cooktops.
सूत्र
The calculator applies EMF = -dΦ/dt
- EMF
- -dΦ/dt — -dΦ/dt
चरण-दर-चरण मार्गदर्शिका
- 1Enter magnetic flux change and time interval

हल किए गए उदाहरण
इनपुट
ΔΦ = 0.1 Wb, Δt = 0.001 s
परिणाम
EMF = 100 V
Rapid flux change induces high voltage
सामान्य गलतियां जिनसे बचना है
- ✕Ignoring the rate of change; steady flux produces no EMF
- ✕Forgetting that area and angle both affect flux
अक्सर पूछे जाने वाले प्रश्न
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.
