Several different methods have been proposed to measure the attractive force of a magnetic attachment since its development. We devised a custom made jig to confirm its validity. However, a more simple method to measure the attractive force was proposed by the Australian magnet research institute in 2009 ISO conference. 　    The proposed method provides reliable measurements in the traction. It can be achieved even for flexible traction using cotton string by controlling the sideslip between a magnetic assembly and a keeper with a simple jig. 　    Five GIGAUSS C 600 (GC) were used as samples, and the attractive force was measured 10 times using EZ-test tensile tester. 　    We compared the results of the attractive force measurement method proposed by Australian magnetic institute with our measurement method.
