Quick Answer. Michael Faraday discovered the law of electromagnetic induction in 1831. He realized that current in a circuit can be induced by changing the magnetic field. Faraday tested it by wrapping a paper cylinder with a wire and connecting the coil to a galvanometer. Faraday then moved the magnet back and forth inside the cylinder.
Tesla Invention Of Radiant Energy. It is no secret that Sir William Crookes was the mastermind behind the discovery of Radiant energy properties. His discovery took place in the year 1875, and since then has prompted others into farther experimentation with solar uses. One scientist Nikola Tesla made some interesting discoveries concerning electrostatic charges and their results. His persistence led to the invention of light that we now call radiant energy. Tesla radiant energy discoveries showed that this type of energy was easily transferable from one place to another. He also proved that light traveled almost the same way as sound does, by sign waves.
