The moving electric charge creates a magnetic field, which fluctuates in strength because the electric current's amplitude is fluctuating. First, alternating current passes through an induction coil in the charging station or pad. Inductive charging is so named because it transfers energy through inductive coupling. The portable equipment can be placed near a charging station or inductive pad without needing to be precisely aligned or make electrical contact with a dock or plug. Inductive charging is also used in vehicles, power tools, electric toothbrushes and medical devices.
It uses electromagnetic induction to provide electricity to portable devices. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. Wireless charging pad used to charge devices with the Qi standard.
