"Faraday’s laws of electromagnetic induction states that when a coil of wire is placed in a changing magnetic field (B) an EMF (E) is induced in the coil and the induced EMF is proportional to the rate of change of flux linkage with the coil (dφ/dt).
E = N(- dφ/dt)
Meaning of the minus sign in Faraday’s law is explained by Lenz’s law which says if the B field changes, the voltage induced in the coil will try to drive a current that produces a B-field which opposes the change(in primary B field)."
Thanks, Could you please elaborate more on what does the negative sign signify?
I need to use some verification sample in ANSYS to calculate generated voltage based on Faraday laws. Which verification sample did I select for ANSYS?
