Magnetic force measuring device and magnetic measuring method

摘要

Problem to be solved: to provide a simple and accurate measurement of the attractive force or repulsive force acting on two opposing magnetic poles.The magnetic force measuring apparatus 10 includesMovable part 11A housing part 12 having a bottom portion 12b disposed below the movable part 11 andDisposed between the upper surface of the bottom portion 12b of the housing part 12 and the lower surface of the movable partThe first load cell 13 fixed to the upper surface of the bottom portion 12b of the housing part 12 andThe second load cell 14 fixed to the upper surface of the movable part 11 andThe preload imparting portion 22 contacting the upper surface of the second load cell 14 and.The first load cell 13 and the second load cell 14 are disposed at positions opposed to each other with the movable portion 11 interposed therebetween, and the pre load imparting unit 22 is used to prepress the first load cell 13 and the second load cell.Diagram
