The sight of two powerful magnets colliding with each other


Two permanent magnets with a pull of 300kg, if they collide with each other at 320km/h, they will create an unexpected scene that many people have never seen before.

Neodim is an extremely strong permanent male composed of an alloy of the rare earths neodymium, iron and boron – combined to form Nd2Fe14B. They are used to replace many old magnets still used in modern electronics.

Neodymium magnets are not the strongest magnets in the world. That title goes to two magnets located at Los Alamos National Laboratory in New Mexico and Florida State University, which can reach strengths of 100 Tesla and 45 Tesla, respectively (magnetic induction unit, 1 Tesla =) 20,000 times Earth magnetic field units). For comparison, the magnet used in the above test has a strength of about 1.3 Tesla only.

The sight of two powerful magnets colliding with each other is horrifying

In the video, 2 neodymium magnets only have a bottom diameter of 7.2cm, a height of 6cm, weigh 1.8kg but have terrible attraction (and repulsion), up to 300kg. That is, to be able to make these two magnets touch each other, we will need to use a weight of 300kg. It can keep a person suspended in the air, if he stands on another magnet.

Permanent magnets made from compounds or alloys of rare earth elements and transition metals are collectively known as rare earth magnets. This type of magnet is much stronger than traditional magnets such as ferrite magnets, AlNiCo magnets. And Neodymium magnet, made from a compound of Neodymium (Nd) – Iron (Fe) – Bo (B), with the molecular formula Nd2Fe14B is the strongest type of permanent magnet known.
