A circular coil of radius 0.100 m contains a single turn and is located in a constant magnetic field of magnitude 0.240 T. The magnetic field has the same direction as the normal to the plane of the coil. The radius increases to 0.290 m in a time of 0.0900 s. (a) Determine the magnitude of the emf induced in the coil. (b) The coil has a resistance of 0.640 2. Find the magnitude of the induced current.
