First appearance of this importent paper, the first paper by Rutherford published in England, in which he describes his invention of the "Magnetic detector" before Marconi made use of it in his wireless telegraphy across the Atlantic in 1901.

On his arrival at Cambridge (in 1895) his talents were quickly recognized by Professor Thomson. During his first spell at the Cavendish Laboratory, he invented the detector for electromagnetic waves, an essential feature being an ingenious magnetizing coil containing tiny bundles of magnetized iron wire. The detector made it possible to send wireless signals.
