Zusammenfassung:A user input device uses an alternating magnetic field, which is configured to accurately transmit and process a location, a direction and the like requested from a user by using the alternating magnetic field. The user input device using the alternating magnetic field includes a power source, a magnetic field generation unit, and a control unit which receives power and controls the magnetic field generation unit involved in generating and blocking the alternating magnetic field. Also, an electric apparatus includes a magnetic field sensor that detects the alternating magnetic field from the user input device.
