Question 2 (1 points) (#848279) (Faraday's Law} A 50-turn coil has a diameter of 15 cm. The coil is placed in a spatially uniform magnetic field of magnitude 0.500 T so that the plane of the coil makes an angle of 30 with the magnetic field. Find the magnitude of the emf induced in the coil if the magnetic field is reduced to zero uniformly in 0.101 s. Please enter a numerical answer below.
