This project is made using electronic circuitry that converts AC 230V 50Hz to AC 12V, High frequency and this HF output becomes input for tuned coil and make a primary for air core transformer and when a secondary coil is brought near, it develops the high frequency of 12V powering connected device. Here the primary coil act as a transformer and secondary as a receiver and power is transferred wirelessly within distance of say 3cm. We can design a mobile/battery charger.
