Neodymium Magnet  are the most common items in people’s real life. Magnets have a wide range of applications. They can be used in industry, manufacturing, and electronic products. Even the entire earth can be understood as a huge magnet. The magnetic north pole is It refers to the south pole of the earth, and the geomagnetic south pole refers to the north pole, while the magnetic poles of the same name repel and the magnetic poles of different names attract.

Magnets are not artificially invented, but natural magnetite. The ancient Greeks and Chinese discovered magnetic ore from nature. This kind of stone can easily suck up some small stones like magic, and always Is pointing in a fixed direction.

Later, people used magnets in navigation. Ancient China also developed the "compass". Later, this invention became one of the four great inventions in ancient China, and it has been passed down to this day.

Neodymium magnets are currently unknown commercial magnets with the highest performance. They are called the Magneto. Its magnetic energy product is more than 10 times that of ferrite, and it can withstand substances that are more than 640 times larger than its own weight. Moreover, its magnetic force is also low. It has super lethality, and in order to verify how strong the magnetic force of the neodymium magnet is, the scientists used several objects to do experiments.

The content of the experiment is very simple. People put two magnets with opposite magnetic poles on both sides, and then put some objects in the middle of the two magnets to test the strength of the female.

Scientists explained that neodymium magnets can crush several tons of objects, and if the experiment is not an apple, but a human body, even human bones can be easily crushed under the magnetic force of the neodymium magnet.
