If the magnetones are used continuously for an hour, there will be aslight warmth developed, on account of the resistance of the wire to thecurrent in a short circuit. My explanation of the heating of the pipe, is that the iron being elasticand .soft, allows the particles of iron in it to vibrate, and knock together, and THE EI.KCTRO-THERAPEUTIC GUIDE 175 it is due to this pounding together that the heat is generated, the same asheat is generated by pounding on iron with a hammer.
