Inductive Power Transmission
Author(s): Sudhanshu Garg, Farhan khan
Abstract: Technology trends are moving toward a completely wireless and mobile world, and our device chargers have followed suit. Inductive charging (wireless charging) may one day replace plugs and wires similar to how Bluetooth and Wi-Fi have modernized personal communication. The idea rets on inductive coupling that uses an electromagnetic field which transfers energy from the transmitter to the receiver. An alternating current passes through the coil in the charger, which engenders a fluctuating electromagnetic field. When the coil in the contrivance is placed inside this electromagnetic field, a current is induced in the coil, which then charges the contrivance's battery. This is why wireless charging is sometimes kenned as inductive charging.
