Scientific Introduction Of Neodymium Disc Magnet Manufacturer

  N52 & Sm2Co17 Rare Earth Magnets are attracted to the side of the refrigerator, and the gravity of the earth pulls it down. Therefore, the magnet must have the energy to overcome gravity, so where does its power come from? Let us first analyze the force state of the magnet. When the magnet is attracted to the side of the refrigerator, it is in a static state. According to Newton's first law of motion, the resultant force on a fixed object is zero.

After a simple analysis, we can conclude that in this state, the magnet will be subjected to 4 forces, namely the electromagnetic force between the magnet and the side of the refrigerator (these are two forces), the gravity force and the one between the sides of the magnet and the refrigerator. Friction between. These four forces are opposite to each other and balanced with each other, so the magnet is in a static state.

Therefore, we can draw a conclusion: "The magnet is adsorbed on the side of the refrigerator and will not fall for decades." This phenomenon is a force balance phenomenon, and the reason comes from the competition between gravity and electromagnetic force. Where does electromagnetic force come from? Here, we have a simple science.

   Neodymium Disc Magnet Manufacturer’s atoms are composed of nuclei and electrons. The nucleus is positively charged, and the electrons are negatively charged. Inside the atom, electrons are constantly moving around the nucleus, and are also constantly rotating. Since the moving charge will form an electric current and generate a magnetic field, the movement of electrons will generate a magnetic field. In most materials, the movement of electrons is chaotic.
