Faraday managed to build two different motors, the first was the homopolar motor. With it, continuous circular motion is engendered by circular magnetic force, around a wire that extended into a pool of mercury. A magnet was in the pool and the wire would then rotate around the magnet if supplied with current from a chemical battery.
This was the foundation of modern electromagnetic technology. Clearly, due to his impressive discovery and invention, Faraday wanted to publish his findings. However, in his excitement to get the work out to the public he did not acknowledge his work with either Wollaston or Davy. This turned into a major issue at the Royal Society.
Not only did it strain the mentor/apprentice relationship Faraday had with Davy, it likely resulted in the issues that followed for Michael. It is said that Davy and/or the Royal Society, pushed Faraday out of the electromagnetic work and research he made their biggest discovery in. He was sent into other assignments regarding a multitude of activities.
