Historical Connections
Michael Faraday was a British chemist and physicist who study the electromagnetism and electrochemistry. The Homopolar Motor was the very first electrical motor to be built. It was demonstrated by Michael Faraday in 1821 in London at the Royal Institution. First he went on and build two devices that can produce on what he called "electromagnetic rotation". This was known as the homopolar motor this caused a nonstop circular motion rising up the circular magnetic force around a wire the stretch to a pool of mercury that is placed in the magnet. Then the wire rotated around the magnet that is supplied with the current from a chemical battery. Michael also built the first electric motor that uses mercury that is a toxic substance. In this experiment it is a less toxic version of Michael Faraday motor out of material that can be found anywhere. The homopolar motor can be made out of a single AA battery or C battery, a single neodymium disc magnet and a piece of copper wire. Although there was no confirmation of what he used.Their are two magnetic poles provided by the single permanent magnet that is used to produce the magnetic field, that also required to generate rotational movement.
He discovered the principle of the homopolar motor and it is called the Lorentz Force. The conductor (wire) current is flowing through the magnetic field that is perpendicular to the current that is feeling a force to a perpendicular direction to the magnetic field and the current. The experiments and inventions formed a foundation of modern electromagnetic technology. Although he did help a Danish physicist and chemist Hans Christian Orsted who discovered the electromagnetism. Humphry Davy and British scientist William Hyde Wollaston have tried to design the electric motor but failed. When Michael Faraday experiment worked forming the foundation of modern electromagnetic technology. He decided to published his work without mentioning the work of Davy and Wollaston. Humphry Davy was a British chemist he was know for being the greatest chemist and inventor in Great Britain. He was know for discovering alkali and alkaline earth metals and the contributions to the findings of elemental nature of chlorine and iodine.
William Hyde Wollaston was a famous English chemist and physicist who discovered the two chemical elements: palladium,rhodium, and the develop the way to process platinum ore. He worked in many advanced fields this include crystallography. optics, and electromagnetic phenomena. He observe the lines of the solar spectrum that laid the foundation for spectral analysis, the discovery of multiple elements, and the creation of the quantum theory in the twentieth century. In 1806 he became the secretary of the Royal Society and in 1813. Later in 1820 he became president after previous president Joseph Banks passed away.He invented a slide rule helping chemist determine the quantities of different chemicals that could combine together. By 1807 he invented the lucida camera that produced the image of a greater clarity than a prodecessor. The camera can obscura is used by many artist to trace images. In 1809 he created the reflected goniometer and the used the reflection of the the light from crystals to measure angles that make one another.
