Achievements
Michael Faraday was known for his significant discoveries, mainly to do with electromagnetism. Many of these paved the way for other important discoveries and inventions in the future. Faraday also invented many devices, some of which are still commonly used today.
Electrolysis
In 1834, Michael Faraday created his two laws of electrolysis. This refined the previous explanation of electrolysis because it took a more systematic approach. Electrolysis is commonly used in refining ores today.

Faraday Cage
Michael Faraday invented the Faraday cage. It is a simple device that blocks electromagnetic radiation. Faraday cages are often used today to conduct sensitive scientific experiments in a controlled environment.

Electric Motor
An early version of the electric motor was invented in 1821 by Michael Faraday. Although it was not powerful enough to do anything useful, it was an important proof of concept. Later, this prototype was developed by other scientists into a revolutionary device that is used today for a variety of different tasks.

Faraday Disc

The Faraday disc is an electric generator that is capable of generating direct current from rotation (dynamo for short). This was the first electric generator ever, and it showed how the relationship between electricity and magnetism could be used to generate electricity. This concept can be seen being used today in bicycle dynamos that allow cyclists to charge their phones or other devices while biking.
