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- T magnetic field. Varying this magnetic field magnitude changes the flux through an 18.0-turn circular loop in the device, creating an emf that charges its battery. Suppose the loop area is 4.00 x 10 4 m and the induced emf has an average magnitude of 5.30 V. Calculate the time required (in s) for the magnetic field to decrease to zero from its maximum value. i... . ..5. HINT Apply Faraday's law. Click the hint button again to remove this hint
