PURPOSE:To reduce an eddy current loss as much as possible and to make the taxiway excellent to a magnetic characteristic by providing the arrangement of a flaky and particulate amorphous metal or crystalline metal having a high magnetic permeability on the way along the way surface to induce the proceeding direction of a vehicle or instruments equipped with a magnetic sensor. CONSTITUTION:Along a way surface to induce the proceeding direction of the vehicle or instruments equipped with a magnetic sensor, the arrangement of a flaky and particulate amorphous metal or crystalline metal having a high magnetic permeability is provided on the way surface. This is to minimize the loss due to the eddy current and to use a magnetic characteristic held by the amorphous metal or the crystalline metal. The foil of an amorphous metal magnetic substance or a crystalline metal magnetic substance have generally a high magnetic permeability and a low magnetic loss and it cannot be said that the eddy current loss is not generated completely. The absolute quantity of a magnetic metal including the amorphous metal and a crystalline metal is not decreased, the eddy current loss is suppressed low, and therefore, the flaky or particulate magnetic metal is used, this is arranged in every direction, the fabrication is executed in a tape shape and it is provided on the way surface as a magnetic sign. |
