The reason why the neodymium magnet does not move even if pressed with tremendous pressure



I crushed the Lego block,Crush the diamondsAnd press machine active in crushing various things. But before that, the most powerful neodymium magnet among the permanent magnets stood up.

Finally, Something a Hydraulic Press Can not Crush

I fought with the magnet, I crushed Lego and Diamond before.Hydraulic Press ChannelAnd,PressTubeA channel called. The point is that using a hydraulic press machine to crush a variety of things is the same.

Hydraulic Press | Large Neodymium Magnet 60 * 60 * 30 - YouTube


This time we use this 60 mm × 60 mm × 30 mm and 800 g of neodymium magnet.

First of all I will set it in the press machine ......


Neodymium magnet stuck to the bolster plate (lower base) snugly.


Then switch on the press machine.


Normally, the upper part (slide) crushes the object, but as soon as it approaches to some extent, the bolster plate rises with the power of the neodymium magnet.


As for the press machine, the slide continues to descend and starts pressing.


At the upper right of the screen there is a pressure gauge, about 9000 lbf / in² (Weight pounds per square inch) Is under the influence of power. I heard a sound like Paki Paki but I can not see changes such as cracking in the magnet.


Unfortunately we could not close the neodymium magnet with this press. I began to raise the slide there, but the neodymium magnet did not leave and the bolster plate and the plate under it lifted again.


First of all, we remove the board that lifts up the bolster plate by pinching it, but it is not easy as it is being drawn strongly again.


I will remove gloves and manage them one by one.


It is also a scene where the board once removed comes close to the bolster plate and is attracted to the neodymium magnet again.


It is unknown how to remove the neodymium magnet after this.


So, why the press machine could not crush the magnets, this is Jinfang Liu, COO of Electron Energy, a leading magnet manufacturer, said: "Compressive strength of neodymium magnets is 130,000 lbf / in² That's why "that answers clearly. In particular, slowly, if pressure is applied equally to the whole, it seems that it can withstand even considerable pressure. According to PressTube, if cracking the magnet beforehand, it was able to break.

By the way, although a powerful neodymium magnet is used, Mr. Liu talked about the influence of the magnetic force, "Magnetic force is a physical property, so I do not play any particular role in this case in particular."
