What is electromagnetism?
Electromagnetism describes the relationship between electricity and magnetism. Nearly everyone, at some time or another, has had the opportunity to play with magnets. Most of us are acquainted with bar magnets or those thin magnets that usually end up on refrigerators. These magnets are known as permanent magnets. Although permanent magnets receive a lot of exposure, we use and depend on electromagnets much more in our everyday lives. Electromagnetism is essentially the foundation for all of electrical engineering. We use electromagnets to generate electricity, store memory on our computers, generate pictures on a television screen, diagnose illnesses, and in just about every other aspect of our lives that depends on electricity. Electromagnetism works on the principle that an electric current through a wire generates a magnetic field. This magnetic field is the same force that makes metal objects stick to permanent magnets. In a bar magnet, the magnetic field runs from the north to th
The interaction of electrical and magnetic effect is known as electromagnetism. Electromagnetism is one of the most important concepts in physical science. An electromagnet consists of a piece of soft iron with electrical wire wrapped around it. When an electric current flows through the wire, it produces a magnetic field around the wire and the iron is magnetized. The greater the current, the stronger the magnetic field. By coiling up the wire many times, the magnetic field produced can be made even stronger.
Electromagnetism is the production of magnetism from electricity ( as the name suggests!! ) A normal magnet has it s strength determined by it s size and the material it is made of. The solenoid has it s strength determined by the current voltage flowing through it and the amount of turns it has. But the electromagnet has it s strength and field determined by the current, the amount of turns and the core shape and substance.
