Question: Inductive charging is used to wirelessly charge electronic devices ranging from toothbrushes to cell phones. Suppose the base unit of an inductive charger produces a1.50

Inductive charging is used to wirelessly charge electronic devices ranging from toothbrushes to cell phones. Suppose the base unit of an inductive charger produces a1.5010³Tmagnetic field. Varying this magnetic field magnitude changes the flux through a12.0-turn circular loop in the device, creating an emf that charges its battery. Suppose the loop area is3.2510⁴m²and the induced emf has an average magnitude of5.30V.Calculate the time required (in s) for the magnetic field to decrease to zero from its maximum value.
