SINCE it was thought that interesting experiments might be performed if it were possible to measure quantitatively persistent currents in a supraconducting circuit much smaller than have so far been ...

Discovery and understanding of electromagnetic induction are based on a long series of experiments carried out by Henry and Faraday. If North-pole of a bar magnet is pushed towards the coil, the ...
