Inductive Charging

Definition

Inductive charging is a method of wirelessly transferring energy through electromagnetic fields to charge batteries or power devices. This process relies on the principles of electromagnetic induction, where an alternating current in a primary coil generates a magnetic field that induces a current in a secondary coil, allowing for efficient energy transfer. In the context of microphysics of clouds, this concept can help explain the charging processes that occur within cloud droplets and the resulting electrical phenomena like lightning.
