Answer to Question #121491 in Electricity and Magnetism for Mahi

Question #121491

Two coils have mutual inductance of 3.25 x 10-4
. The current in the first coil
increases at a rate of 830 A/s. What is the magnitude of the induced emf in the coil?

Expert's answer

$e.m.f.=M\frac{di}{dt}=3.25\cdot10^{-4}\cdot830=0.27V$
