Hi.
The induced emf is given by -d/dt ∫B.dS but when the time derivative is taken inside the integral sign this becomes -∫ ∂B /∂t.dS .
Why isn't B.dS differentiated using the product rule giving an extra term inside the integral sign ?
For some reason the integral sign is appearing as a small circle in the above equations
