Electric power is impossible to imagine in the world. Wires are typically used to transmit power. Envision a future in which wireless power transfer is probable: Mobile phones, household robots, digital audio players (DAPs), laptop computers, and bearable electronics can charge themselves, freeing us from the need to be joint to a power source by a wire. A wireless mobile charging system using the electromagnetic field is intended to clarify its concept by elucidating it. Users can charge their mobile phones wirelessly in this system without the need to plug in the mobile adapter. A charging pad demonstrates the process of charging a mobile phone, requiring users only to place their adapter circuit on it. The transmitting and receiving parts of this system are designed and built as two distinct entities, each utilizing a coupling electromagnetic field. The oscillation circuit converts DC energy into AC energy, which in turn induces a magnetic field by passing through a frequency. This causes the receiver coil to be induced with an alternating current. The magnetic field coupling between the transmitting coil and the receiving coil can be calculated using Ampere’s law, Biot-Savart’s law, and Faraday’s law. In this paper, The ability of the wireless mobile charger is calculated by varying the space between the coils in a system that utilizes an electromagnetic field for charging wirelessly.
