Innovations Introduction to Copper Mining Extraction

However by far the greatest extension in the use of copper resulted from Michael Faraday s discovery of electromagnetic induction in 1831 and the way that the effect could be used to generate electricity The same principle was used to develop electric motors The electric lamp was invented by Sir Joseph Swan in 1860 and brought to a commercial design by Thomas Edison in 1879
