Magnet is one of the most common items in our daily life. It has a wide range of applications and can be used in industry, manufacturing, and electronic products, etc. Magnets can be divided into two categories, namely permanent magnets and non-permanent magnets, and permanent magnets can be natural magnetite or artificially made magnets. Among all permanent magnets, the strongest is the neodymium magnets. This type of magnet is called the King of Magnets. Then how strong are neodymium magnets?
The magnetic energy product (BH)max of neodymium magnets is more than 10 times that of ferrites, and it can suck substances more than 640 times their own weight. In our everyday life, the magnet’s magnetism usually does not harm humans, but if it is the most powerful magnet on earth, this is another matter.
In fact, the magnetic force of the neodymium magnet has super lethality, and in order to verify how strong the magnetic force of the neodymium magnets are, scientists did the following experiments.
The steps of the experiment are very simple. Just put two neodymium magnets with opposite magnetic poles on both sides, place some objects in the middle of the two magnets, and then release the two magnets to test the strength of the magnetism.
First, they placed a can of Coca-Cola between two neodymium magnets. The moment the neodymium magnets were released, the can of Coke was instantly crushed by a powerful force, scattering the Coke all over the place.
After that, they also used an apple to do the experiment to test how strong neodymium magnets can be. Unexpectedly, after the magnets were released, the apple was squeezed and deformed little by little under the magnetic force of the neodymium magnets, and finally, the whole apple was crushed into dozens of pieces.
They explained that large neodymium magnets can crush objects weighing several tons. Therefore, if the object used in this experiment is not an apple but a human’s body, then such a strong magnetic force of the neodymium magnets will cause lethal harm to the human body, and even easily crush the human bones.
It can be seen from the above two experiments that the magnetic force of the neodymium magnets is super strong. Thus, when using this kind of magnets, we must take extra care to prevent harm to ourselves due to improper use.
Thank you for reading our article and we hope it can help you have a better understanding of how strong are neodymium magnets. If you want to know more about neodymium magnets, we would like to recommend you to pay a visit to Stanford Magnets for more information.
Stanford Magnets is a leading magnet supplier across the world, who has been involved in R&D, manufacturing, and sales of magnets since the 1990s. It provides customers with high-quality rare earth permanent magnetic products such as neodymium magnets, and other non-rare earth permanent magnets at a very competitive price.
