Electromagnetic induction
James Maxwell
James clerk Maxwell was a physicist who’s research was focused on electrical and magnetic phenomena.
James Maxwell’s greatest contribution was the electromagnetic theory where he proved that electricity is related to magnetism. He did this by looking back on Michael Faraday’s experiment with iron fillings and magnets and doing an experiment where “he discovered that an electric current flowing in a wire caused "lines of force" to expand outward, inducing an electric flow in an intervening wire”( World of Scientific Discovery. GALE). Then recognizing the relationship between electricity and magnetism he used “a few simple equations” (World of Scientific Discovery. GALE) to prove his idea.
Through his initial discovery he found the speed of expansion to be almost the same as the speed of light, and through that determined that light was a form of electromagnetic radiation. He also recognized that because the velocity could be changed in to an infinite number of velocities there were an infinite number of corresponding types of electromagnetic radiation, so the visible spectrum is only a small portion of the possible types of electromagnetic radiation.
We are able to apply his work today through communications such as the radio and television.

Induction cooktops
Coils under the surface of the cook top carry an alternating current making a changing magnetic field This field reacts with "iron-rich cookware" and the current is converted to heat within the "cookware".
This allows for quicker and more even cooking. (Gerbis)
