Suppose the base unit of an inductive charger produces a 1.50 x 10-ST magnetic field. Varying this magnetic field magnitude changes the flux through a 17.0-turn circular loop in the device, creating an emf that charges its battery. Suppose the loop area is 4.00 x 10-4 mand the induced emf has an average magnitude of 5.20 V. Calculate the time required (in s) for the magnetic field to decrease to zero from its maximum value.
