An embodiment of the present invention relates to a sensor array. The sensor array comprises a structure of a disk shape having multiple magnetic elements provided on at least end surface of the structure of the disk shape. The sensor array comprises a hollow disk structure including two end surfaces and multiple tooth parts in which each of the two end surfaces of the hollow disk structure is mutually separated, wherein the tooth parts of the two end surfaces are oppositely arranged. The tooth parts on each identical end surface of the hollow disk structure are mutually separated. The structure of the disk shape is able to be rotated around the hollow disk structure. The electromagnetic sensor is provided in order to detect magnetic fields generated by multiple magnet elements. |
