Electromagnetism is the interaction between magnetic fields and either electric fields or currents. Michael Faraday was the physicist who brought this phenomenon to the scientific world. It turns out that a current is produced when there is a change in a magnetic field. When looking at a circular electric wire connected to an ammeter, a magnet moving towards the wire causes a positive current. Where as when the magnet is not moving, there is no current. Moreover, the ammeter shows a negative current when the magnet moves away from the electric wire. Alternatively, when the wire is moved and the magnet is held stationary, a current is also produced. All of the following scenarios fall under electromagnetic induction. Electromagnetism brings

In terms of the history of electricity, the observance of the effects of electricity began with the Ancient Greeks. Real progress began with an Italian physicist Alessandro Volta. He discovered that a particular chemical reaction could produce electricity. Moreover, Michael Faraday, Thomas Edison, and Nikola Tesla all contributed to the development of efficiently using the phenomenon of electricity. Key concepts of electricity include its definition, classifications, and the electric field. To define, electricity is a form of energy from the existence of charged particles. Moreover, electricity is classified as static and current. In addition, the electric field is present in any region where a charged object experiences an electric force. Moving on to magnetism, the history of magnetism is just as brief as electricity. The ancient Chinese were the first to pave the way for the use of magnets. That is to say the Chinese were responsible for launching the use of the compass because they figured out how a needle coated with lodestone. This discovery led itself into Europe and opened the doors of uncovering the mystery of earth’s magnetic field. When it comes to key points, its important to reconcile the definition of magnetism, its natural qualities, the magnetic field, and magnetic materials. To begin with its definition, magnetism is defined as either an attractive or repulsive force between objects due to an electric charge. When it comes to the natural qualities of magnets, the magnetic force always follows a circular path. Moreover, magnetic fields are simply an area of space that undergoes magnetic influence. Lastly, magnetic materials are categorized as paramagnetic or diamagnetic materials. As for electromagnetism, its history generally began with Michael Faraday. He studied the phenomenon of an electric current becoming produced by a change in a magnetic field. Key points related to
