When the current in one coil changes at a rate of 8.5 A/s, an emf of -9.5 x 10- V is induced in a second, nearby coil. What is the mutual inductance of the two coils (in H)? H Additional Materials Reading [-/3 Points] DETAILS OSUNIPHYS1 30.1.P.024. MY NOTES ASK YOUR TEACHER A 40-turn coil has a diameter of 17 cm. The coil is placed in a spatially uniform magnetic field of magnitude 0.40 T so that the face of the coil and the magnetic field are perpendicular. Find the magnitude of the emf induced in the coil (in V) if the magnetic field is reduced to zero uniformly in the following times. (a) 0.30 s (b) 3.0 s (c) 55 s
