1. A mobile device comprising:
- a main body having a metallic element mounted thereon; and
an expansion module electrically connected to the main body,wherein the expansion module comprises;
a holder configured to be coupled to the main body;
a magnet mounded at the holder and disposed to apply a magnetic force to the metallic element to couple the expansion module with the main body; and
an input device configured to allow input of a control command to the main body when the main body is coupled to the holder of the expansion module.

Abstract
A mobile device includes a main body having a coupling element mounted thereon, and an expansion module electrically connected to the main body, wherein the expansion module comprises a magnet disposed to apply a magnetic force to the coupling element to couple the expansion module with the main body, and a movement converter configured to move the magnet away from the coupling element so as to decrease the magnetic force between the coupling element and the magnet thereby decoupling the main body from the expansion module.

17. An expansion module for a mobile device comprising:
-
an expansion body detachably coupled to one surface of the mobile device; a magnet disposed at the expansion body to apply a magnetic force to a coupling element in the mobile device thereby coupling the expansion body with the mobile device; and a movement converter configured to move the magnet away from the coupling element so as to decrease the magnetic force between the coupling element and the magnet thereby decoupling the mobile device from the expansion body, wherein the movement converter comprises; a manipulation member disposed at the expansion body; a rotation generator configured to rotate the magnet when the manipulation member is manipulated; and a sliding generator configured to slide the magnet along an axial direction of a rotation of the magnet when the magnet rotates.
