A rotating magnet is magnetized to have an S2 pole and is rotatably arranged in a composite magnetic field that combines the magnetic fields generated by each of the pair of coils, and a pointer shaft that is fixed to a pointer shaft that is rotated by the rotation of the rotating magnet. In a crossed coil type indicator having a pointer, the weight is adjusted around the pointer shaft so as to generate a rotational torque that resists the rotational torque generated by the interaction between the earth's magnetism and the NS2 pole of the rotating magnet. A crossed coil type indicating instrument characterized by having a difference.
