5. Inductive charging is used to wirelessly charge electronic devices ranging from toothbrushes to cell phones. Suppose the base unit of an inductive charger produces a 1.50 x 10^-3 T magnetic field. Varying this magnetic field magnitude changes the flux through a 16.0-tum

circuler loop in the device, creating an emf that charges its battery. Suppose the loop area is 2.75 x 10^-4 m² and the induced emf has an average magnitude of 5.50 V. Calculate the time required (in s) for the magnetic field to decrease to zero from its maximum value.
