A magnet, kept in a secured room at Tokyo, exploded by literally cracking the room’s door. This electromagnet is one of the kinds that generates a magnetic consisting of a flow of electrical current in it. The moment the Scientists switched-on the magnet, it propelled the heavy doors which were actually designed for safeguarding it.
The recently published study in the journal – Review of Scientific Instruments showed that the strength of the magnetic field which is measured in a unit of magnetic intensity ‘tesla’ turned out to be as high as 1200, equivalent to more than 400 times powerful than that of an MRI machine.
More than a decade ago, a magnet with an intensity of just 45 teslas was described by the journal named Popular Mechanics magazine as the most powerful magnet, which means a magnet that after turning on does not tear itself into bits. This magnet, however, is as less as 4 percent of the power emitted by this 1200 tesla intense magnet, created by Shojiro Takeyama and his team.
For achieving this level of intensity, Takeyama along with his team has pumped megajoules of energy into a petite electromagnetic coil, which is the inner lining of the magnet that collapses the magnetic field inside gets squeezed into a tighter space.
Discussing one of the experiments, from1960s to 2001, by the Russian and American Researchers in which the electromagnet created an energy of around 2,800 teslas, Takayama said:
“The most similar magnetic-field generation is by chemical explosives. They cannot conduct these experiments in indoor laboratories, so they usually conduct everything in the outdoors, like Siberia in a field or somewhere in a very wide place at Los Alamos, New Mexico.”
He added, “And they try to make a scientific measurement but because of these conditions it’s very hard to make precise measurements.”
