Faradays Law ची गणना कशी करावी
Faradays Law म्हणजे काय?
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 मार्गदर्शक
- 1Enter magnetic flux change and time interval
- 2The calculator applies EMF = -dΦ/dt
- 3Results show induced voltage magnitude
Worked Examples
इनपुट
ΔΦ = 0.1 Wb, Δt = 0.001 s
परिणाम
EMF = 100 V
Rapid flux change induces high voltage
Common Mistakes to Avoid
- ✕Ignoring the rate of change; steady flux produces no EMF
- ✕Forgetting that area and angle both affect flux
Frequently Asked Questions
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.
