What is Electricity and Magnetism?
Current is the flow of electrical current or charge. It is both an integral part of nature and one of our most used forms of energy. “Electric” comes from the word “electron” the word for particles or “electron”, which refers to a negative derivative to a positive terminal through a conductor, creating an electrical current. Electricity is actually a secondary source of energy from coal, hydro, wind, solar or nuclear power and other sources such as batteries, commonly used in scientific experiments can be derived. Electricity is also a natural phenomenon that, in the form of static electricity, like lightning. Before the man of power was available 100 years ago, oil lamps were used as light source and the houses were heated with wood or coal stoves.
But wait, this section of electricity and magnetism! So what to do with magnetism and electricity? This is because the power of a unique relationship with magnetism. One of the four fundamental forces of the universe “, the electromagnetic force. Principle can not have electricity without magnetism, and vice versa. This does not mean that electricity and magnetism are exactly the same, but they are close on a more intimate relationship. Indeed, magnetism and electricity are so closely related that another reason!
Magnetism in a broad sense, the ability of a magnet to attract magnetic materials, but many similarities between magnetism and electricity. A magnet has two poles, like North and South Poles, while the electricity has two terminals called a negative and a positive pole. Opposite magnetic poles attract and similar magnetic poles repel each other, like electric charges. Current magnetic field generated by electric and magnetic effects. The relationship between electricity and magnetism called electromagnetism.
Electricity and magnetism is one of the major branches or parts of scientific studies. Science is really simple and really only on the understanding of the world you live in. It can not scientists studying all aspects of this world we live in and many different areas of science that exists, it is all a bit overwhelming if not divided into categories. Categories, such as electricity and magnetism, so the researchers at a number of related issues and to communicate with others interested in similar problems and can better understand the science.
Electricity and magnetism can be separated into several sub-sectors such as: static and current electricity and magnetism in the resistance, among others. Each sub-sector, in turn, more specific areas. Electricity and magnetism is the focus of research and teaching in the course of history, and despite its importance in our daily lives that we hardly ever stop to think what would life be without electricity. Even if we keep electricity for granted, it is used to improve our lives in many areas of lighting, heating and cooling our homes to power our TVs, computers and other devices that we depend on every day!
