To achieve the purpose, according to the present invention, an electromagnet is inserted into a globe, and a permanent magnet is installed at both ends of the rotation axis of an electro-permanent magnet. First, to see the globe, a globe support is folded down and a current is sent to make the electromagnet indicate magnetic properties, and then, the globe is floated, and the electro-permanent magnet is not used as the magnetic properties disappear. To stop seeing the globe, the globe support is unfolded, and the current is stopped. Thus, the electromagnet is not used, and the electro-permanent magnet includes the globe support (rotation axis). The present invention provides an electromagnet and electro-permanent magnet globe enabling a user to see the globe floated through the electromagnet and the electro-permanent magnet while preventing pain in the neck.
