Wireless charging explained: What is it and how does it work?

A full guide to wireless charging, including how it works and the best models to buy

Definition of inductive charging

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 1.00 ×10^-3- T magnetic field. Varying this magnetic field magnitude changes the flux through a 15.0 -turn circular loop in the device, creating an emf that charges its battery. Suppose the loop area is 3.00 ×10^-4 m^2 and the induced emf has an average magnitude of 5.00 V . Calculate the time required for the magnetic field to decr
