Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...
H. P. J. WIJN and others 1 have described a novel method of making ‘Ferroxcube’ with a square hysteresis loop. Glass with a higher coefficient of expansion than the ‘Ferroxcube’ was fixed to a ...
