What is electromagnetic physics?
electromagnetic physics seeks to explain the interaction of electrically charged particles and magnetic phenomena. Although it was originally considered separate, it turned out that electrical and magnetic fields were related. With the exception of gravitational effects, the electromagnetic force follows almost all natural interactions observable by the naked eye. Whether electromagnetic physics is essentially associated with other areas of physics is the topic of ongoing research.
British physicist James Clerk Maxwell in 1873 showed that electricity and magnetism were connected. He showed not only how the charged particles interact, but also how moving charges create magnetic fields. His hypotheses have since been extensively confirmed by experiment. Since then, electromagnetic physics has been considered one theory; This is embodied in a set of four laws known as Maxwell's equation.
There are four basic forces in nature - electromagnetic, gravitational, strong nuclear and weak nuclear forces. Each of themIt takes all distances in the universe, but, like all areas of science, the electromagnetic force has the extent in which it dominates. Gravity dominates on very large scales, such as stars and galaxies. Electromagnetic interactions still occur, but are impressed by gravitational force; In a sense, electromagnetic physics is "drowned".
In extremely small scales, for example in the core of a single atom, a strong nuclear force is dominated. It is a force responsible for maintaining protons inside the core, although the electromagnetic force tends to separate them. This leaves the middle scale, which is largely dominated by electromagnetic physics.
Although the electromagnetic force interacts with each charged particle individually, it is responsible for greater interactions. When the electrons of one atom intertwine with the electrons of another, a molecule can be formed. Molecules can be more stable than someindividual atoms. In addition, the molecules can interact with each other in a process that is fundamentally governed by electromagnetic physics. These molecular exchanges are the basis of chemistry.
recent development in physics has proposed that electromagnetic force may be related to other basic forces. The weak nuclear force, which is responsible for the radioactive break -up, seems to be very different in everyday circumstances from the electromagnetic force. However, it seems that at extremely high temperatures both different forces are combined in what is called electroweak force. In addition, electromagnetic and gravitational forces seem to differ in the same way in space. The possibility that all the basic forces are connected, popularized by British physicist Stephen Hawking and others, is called the theory of any.
