PURPOSE: A power supply device of a mobile communication terminal using an induced electromotive force and its using method are provided to generate a current by using an antenna so as for a user to use a mobile terminal to inform about his/her situation in an emergency when a battery of a mobile terminal has been completely discharged. CONSTITUTION: When a battery of a mobile terminal of a user has been discharged or in a low state, the user inputs a designated button(S1). The mobile terminal user moves vertically or rotates an antenna of the mobile terminal(S2).
