A year ago, the world’s most powerful magnet was created… but something happened

The most powerful magnet on the planet was released last year, in September 2018. It represented one of the experiments of the University of Japan, which caused the most uproar in the scientific world. And it is that the potential of this magnet was so enormous, that it showed the figure of 1,200 teslas, which translates to 400 times more intense than what an MRI means.

The bad news is that the same laboratory where this product came to life, ended up destroyed by the same potential of the magnet. In essence, the experiment shattered the laboratory, while the magnet exploded, as you will see in the following video:

How did the Japanese create the most powerful magnet on the planet? There is a diagram published by the University of Japan itself, where you can analyze in depth how the magnet infrastructure was. For this experiment, we worked with a series of capacitors. In this image, you can recognize them in the left zone, in white color.

These capacitors have the virtue of storing up to 5 megajoules. So the energy derived from these capacitors is reflected and flows into the same primary coil, which is what you can identify below, in the left and gray area.

An implosion that happens in 40 microseconds

At the same time, a current and a magnetic field in its coating are induced in the primary coil. This coating can be identified in the image by the color orange. Thanks to all this technology, a coating implosion is generated in a period of 40 microseconds, as you can see in the area below, on the right.

And that is how the power of 1,200 teslas is achieved. Many investigations were carried out on the development of this magnet. One of them focused precisely on the compression of electromagnetic flux, also known as EMFC. With this compression, a magnetic field whose low power was 3.2 tesla could be established.

With the use of capacitors, said the quality of understanding of electromagnetic flux was increased. A good part of the techniques and knowledge implemented in this experiment was reflected in an article published in the Review of Scientific Instrument. Thus, it was possible to know clearly what was the strategy implemented by Japanese researchers.

The team reached 500 teslas more than predicted

By creating the compression of the magnetic field in a fairly small area, it sets a very fast charge level. The problem is that compression cannot be maintained for a long time. So it is natural, or rather, just logical that the experiment generates a shock wave capable of destroying the instrument that contains the load.

The Japanese scientists themselves were clear that this was going to happen sooner rather than later. In fact, it was estimated that the explosion would break out as soon as the equipment reached 700 teslas. However, the explosion was unleashed only until the magnet conquered the 1,200 teslas. One of the researchers, Mr. Takeyama, very wisely explains what this phenomenon offered.

In his words, what happened was the result of behavior derived from electrons. When these are outside the same materials, it is possible to identify their reactive motion. Through a specific light, you can then see how they act in front of the devices.

What is the purpose of this experiment?

Yes, what was the purpose of establishing this experiment? What is the use of having created the most powerful magnet in the world? These are the classic questions that a person usually asks himself when science goes to create “inventions”, which rather than “inventions” seem like technical experiments to challenge the reality and limits of the imagination.

The truth is that the creation of this magnet was not the main goal of the experiment. At the time when the scientists of the University of Japan decided to perform this test, the theoretical intention was beyond the result of obtaining the most powerful magnet in the world.

They did not create this magnet to have fun observing how the objects were brutally attracted by the magnetic force of it. But in advance, in theory, scientists knew that they would produce such a magnet as a result of testing with the magnetic forces and capacitors that would be used.

The purpose of the test was to measure the consequences of the behaviors between the capacitors and the rest of the equipment. And from this test, key aspects could be decided on how electrons interact in their most drastic state.

A contribution to the creation of devices and new technologies

By knowing the limits that an electron can reach in the face of the matter on which it has an effect, new alternatives are opened for technology developers to use this knowledge in sophisticated and efficient equipment that does not tear apart when they reach high rates of behavior.
