Faradays Law کا حساب کیسے لگائیں
Faradays Law کیا ہے؟
Faraday's law relates changing magnetic flux to induced electromotive force. It's the principle behind transformers, generators, and induction cooktops.
فارمولا
The calculator applies EMF = -dΦ/dt
- EMF
- -dΦ/dt — -dΦ/dt
مرحلہ وار گائیڈ
- 1Enter magnetic flux change and time interval
- 2The calculator applies EMF = -dΦ/dt
- 3Results show induced voltage magnitude

ان پٹ
ΔΦ = 0.1 Wb, Δt = 0.001 s
نتیجہ
EMF = 100 V
Rapid flux change induces high voltage
عام غلطیاں جن سے بچنا ہے
- ✕Ignoring the rate of change; steady flux produces no EMF
- ✕Forgetting that area and angle both affect flux
اکثر پوچھے جانے والے سوالات
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.
