This torque cantilever is used to measure magnetic property of bismuth in intense magnetic fields. The bismuth crystal (5.6 mm tall vertical pillar) is glued to the end of a thin cantilever beam made of gold. Deflections of the cantilever in a field are detected by measuring changes in capacitance.
