Paano Kalkulahin si Faradays Law
Ano ang Faradays Law?
Faraday's law relates changing magnetic flux to induced electromotive force. It's the principle behind transformers, generators, and induction cooktops.
Pormula
The calculator applies EMF = -dΦ/dt
- EMF
- -dΦ/dt — -dΦ/dt
Step-by-Step na Gabay
- 1Enter magnetic flux change and time interval
- 2The calculator applies EMF = -dΦ/dt
- 3Results show induced voltage magnitude
Mga Nalutas na Halimbawa
Input
ΔΦ = 0.1 Wb, Δt = 0.001 s
Resulta
EMF = 100 V
Rapid flux change induces high voltage
Mga Karaniwang Mali na Dapat Iwasan
- ✕Ignoring the rate of change; steady flux produces no EMF
- ✕Forgetting that area and angle both affect flux
Mga madalas itanong
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.
