Inductive coupling is a method of transferring electrical energy between two coils through electromagnetic fields. This technology is commonly used in applications like wireless charging for devices such as smartphones and electric vehicles, allowing for convenient power transfer without direct contact. The principle behind inductive coupling relies on the interaction between a primary coil, which generates a magnetic field, and a secondary coil, which receives the energy. This method is efficient and can be scaled for various applications, making it a key component in modern electrical engineering and consumer electronics.
