Rare earth magnets are alloys of rare earth elements and are considered to be the strongest permanent magnets. Rare earth magnets can produce more than 1 compared to other magnets such as ferrite and aluminum nickel cobalt. 4 teslas, while ferrite body magnets and other ceramic magnets can generate a magnetic field from 0. 5 to 1 tesla. The name rare earth magnets does not actually mean that they are rare, but rather they are a readily available resource. There are two types of rare earth magnets; the Samarium - Cobalt and nd. Samarium Cobalt is much more expensive than nd. Because of the cost, it is not used too much, and it also adds the fact that it has a weak magnetic capability. They are weak due to thermal shock and easily break. On the other hand, it has an advantage for those who need high field strength at high temperatures. Nd is better than sm cobalt. The price is reasonable and is the best in the operation of the need for strong and compact magnets. However, it is easily oxidized due to its low dwell temperature. Rare earth magnets can be very dangerous even in terms of health, but it has a variety of uses such as hard drives for computers, speakers, flashlights, motors, led, wind bands, etc. Benjamin Franklin is a scientist known for his theory of electricity. He thinks the current is in the opposite direction. He believes that when the charge actually has a surplus, it needs more electrons, thus finding electricity. When he tested the charge flow from smooth wax to rough wool, it started, where the electron is the unit of charge and it is transferred from wool to wax, not the opposite, finally, it is concluded that the electron has negative or defective charges and positive charges. This is the traditional concept of mobility. Electron flow rare earth magnets are interpreted as current charge flow in the same direction, which is also the natural flow of electrons. Some textbooks introduce this concept, while some professional scientists use the concept of electron flow in solid state physics, which requires showing the real and actual movement and flow of electrons and matter. The advantage of using the electron flow concept is that it accurately shows the natural flow of electrons in materials. If working on a vacuum tube device, the concept of electronic flow is the best option, as they are called vacuum tube devices also called electronic tubes that amplify small electrical signals. In order to visualize and better understand the flow rate of control and application within the path, the electronic flow concept is recommended. The only drawback of electronic motion is that for those who start working as electrical engineers because of their constituent symbols, they can be very confusing. Conventional flowing rare earth magnets will determine the flow of electrons through positive and negative labels. This charge moves from the positive side and is also considered to be a surplus moving to the negative side, also known as the insufficient side. When it comes to determining the exact direction of the electronic motion, it can also be understood as the electronic flow of the concept \"opposite. The traditional flow may be beneficial for those starting with an electronic engineer, as it is less complex when displaying the direction of charge movement in the circuit. In the actual electrical movement, the electrons flow in the same direction, so engineers should not be confused. But in the end, whether you\'re using a traditional or electronic flow concept, there won\'t be any problems with the device. For some people who start physics with a traditional flow concept, for some reason they don\'t want to use the electron flow concept. Those who start using the latter also have the same situation. But it is important to use the consistency of symbols during the render stream to avoid confusion.
