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

ସୂତ୍ର

The calculator applies EMF = -dΦ/dt
EMF
-dΦ/dt — -dΦ/dt

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

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
ΔΦ = 0.1 Wb, Δt = 0.001 s
ଫଳ
EMF = 100 V
Rapid flux change induces high voltage

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

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

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.
