Hans Oersted had a pharmacological background and he also performed experiments in chemistry.In 1819, a year before he discovered electromagnetism, Oersted became the first person to discover the chemical compound Piperine.Piperine is a naturally occurring organic … An electromagnet is a piece of wire intended to generate a magnetic field with the passage of electric current through it. They begin with only minimal guidance, and after the basic concept is understood, are informed of the properties that affect the strength of that magnet. Electromagnetism is a branch of physics that deals with all phenomena of electricity and magnetism. It is governed by a set of fundamental principles encoded in four equations called Maxwell equations, which have been known for approximately 150 years. College of Sciences ...

Browse complete Electromagnetism experiments from PASCO. In fact, Maxwell's equations are consistent with relativity, which was not theorized until 30 years after Maxwell completed his equations. During this experiment, Faraday and Henry observed that relative motion between the coil and the magnet is responsible for induction of electric current in the coil. Maxwell’s Equations. They were a synthesis of what was known about electricity and magnetism, particularly building on the work of Michael Faraday, Charles-Augustin Coulomb, Andre-Marie Ampere, and others.These equations predicted the existence of Electromagnetic waves, giving … Therefore, unlike other waves, an electromagnetic wave is self-propagating, even in a vacuum (empty space). P=Project E=Experiment. Electromagnetism is also used to describe how a magnetic field is created by the flowing of electric current. The meters themselves illustrate the connection … https://www.education.com/science-fair/article/electromagnet Though all current-carrying conductors produce magnetic fields, an electromagnet is usually constructed in such a way as to maximize the strength of the magnetic field it produces for a special purpose.
