Abstract
DURING the last thirty years, the question as to whether electromagnetic induction is caused by the change or by the cutting of magnetic flux has been debated at intervals. Faraday's rotating disk experiment and the later experiments of Blondel1 and of Messrs. Cramp and Norgrove2, as well as Prof. H. A. Wilson's experiments with moving dielectrics3, all appear definitely to favour the flux-cutting hypothesis ; and Rowland's experiments with revolving electrostatically charged disks4 indicated that a magnetic force is similarly induced by the cutting of an electric field. There seems little doubt that Faraday himself believed that electromagnetic induction was produced by the cutting of his magnetic "lines".
