Abstract: A compression molded core contains a plurality of soft magnetic material powders. A first powder and a second powder in the plurality of powders satisfy D1>D2, 0.23?(D1?D2)/D1<0.6, D1?7 ?m, and 3 ?m?DT?5.7 ?m. D1 is the median diameter, which is a particle size at which the integrated particle diameter distribution from the small particle size side is 50% in a volume-based particle size distribution measured by a laser diffraction/scattering method, of the first powder and is maximum among median diameters; D2 is the median diameter D2 of the second powder and is minimum among median diameters; and DT is determined using the weight rate R1 of the first powder and the weight rate R2 of the second powder by R1×D1+R2×D2.

Abstract: An attention attracting device that effectively attracts attention and has improved versatility over a conventional technology, a mobile body including this attention attracting device, and a method for controlling the attention attracting device are provided. A predetermined area including a gazing point of a viewer is set as a central visual field at a time of the viewer directing a visual line, and an area other than the central visual field is set as a peripheral visual field. The attention attracting device includes a light source set to such a frequency F [Hz] that the light source is seen to be turned on in a case in which the light source is present in the central visual field and is seen to be blinking in a case in which the light source is present in the peripheral visual field. The mobile body includes the attention attracting device as a lamp body of a vehicle and emits light from the light source to the outside.
