PROBLEM TO BE SOLVED: To provide a movable magnet-type instrument with a large degree of design freedom in the size of a second gear and the layout of a pointer shaft. SOLUTION: A first rotating shaft 3 comprises both a rotor magnet 1 and a first gear 2 to be rotated together with the rotor magnet 1. A second rotating shaft 5 comprises a second gear 4 to be engaged with the first gear 2. The first rotating shaft 3 and second rotating shaft 5 are supported at a housing 6. A first coil 7 is wound on the housing 6. A second coil 8 is wound on the housing 6 and intersects the first coil 7 at a predetermined angle except 90 degrees.
