<p>The present invention relates to a magnet holder, including: a permanent magnet; a pole piece coupling to one of the N and S poles of the permanent magnet, and having a holding surface; a magnetized material having an end surface contacting the pole piece; a coil surrounding the magnetized material; and a control device controlling electrical current flowing through the coil to control the magnetization of the magnetized material. According to the present invention, optimal holding force can be applied to a unit area, and the magnet holder can be conveniently expanded to a module or be miniaturized according to the size of the interior of a device on which the magnet holder is installed, and can be widely applied to various fields such as lifts, chucks, locking devices, application machines, and robots.</p> |
