Experiments on Supraconductors

In a previous letter1 it was reported that the magnetic induction in tin spheres, which were cooled in an external magnetic field until they became supraconductive, did not vanish entirely, but that part of the magnetic flux remained in the body. This freezing in of lines of force was observed, when supraconductivity was attained either by cooling the specimen in a constant magnetic field or by decreasing the external field at constant temperature. Since then, this result has been confirmed by magnetic experiments by Rjabinin and Shubnikow2 and by calorimetric measurements by Keesom and Kok3.
