1. A method for controlling a user terminal, comprising:
- in response to a user input for generating a magnetic field being received, transmitting a magnetic field generation command to an external mobile terminal;
obtaining reference magnetic field information of the user terminal;
detecting a magnetic field emitted from the external mobile terminal; and
obtaining location information indicating a location of the external mobile terminal based on the reference magnetic field information and the detected magnetic field.
