Abstract
In the pulsed high magnetic field, electromagnetic force is acted on the metallic materials with high electrical conductivity. Using this principle, the evaluation system of strength for materials in the high magnetic fields was developed and tested. Cu and Al-6063 pipes are used in this study. Water-cooled bitter-type pulse magnet is used. Time constant of pulse field is 2.6ms. The pipes are crushed above 10 T, which indicates huge electromagnetic force is acted. From the experimental results, we estimated the electromagnetic force. Obtained centrifugal stress directed to the central axis is quantitatively the same as yield point.
