If we employeda piece of ordinary wire to carry the current, the wirewould tend to coil up into a circle exactly like the /S-ray,and there would be a battle between the natural stiffnessof the wire and the deviating magnetic force, and itwould depend on their relative strengths which care, however, it is possible to use a fluid wire,which has no stiffness. If a strong current is passedthrough a thin aluminium wire it, of course, gets hotand finally melts, but retains its original form withoutbreaking, hanging by virtue of
