Let V_B be the rate of decrease of the magnetic fields
\frac{dB}{dt}
For the 3rd path:
\oint E\cdot ds = -\frac{d\phi _B}{dt} = -\frac{{d\phi _B}_1 + {d\phi _B}_2}{dt}
\phi _B_{(t)} = A_{(t)}B_{(t)}
The area is constant, it's only the magnetic field that's changing:
\phi _B_{(t)} =...
Alright... What are the rules for when the numerator (Top part) of the fraction has a higher degree than the lower part of the fraction.
Something + {*}
... As in what is that SOMETHING based on the numbers?
I have a midterm in like... 50 minutes and this is the only thing I need to know.
