โœฆ Synopsis

We have found that solder coated spring wire brushes can make a sliding superconducting contact with a rotating superconducting commutator. With a relative velocity of 0.5 cm s "I between brushes and rotor, we observe critical currents of up to O. 1A. Below the critical current we detect no resistance above 10 -7 ~t,

Of course, this instrument could be improved by introducing some elementary modifications which we did not undertake, namely. 1. diminishing the transmission of vibrations into the mercury of the manometer; 2. introduction of a thin and small stainless steel circular plate, which would be floating
