Japanese world record for strength

A team of scientists from the University of Tokyo recorded the strongest magnetic field ever created in an enclosed space - as much as 1200 Tesla. By comparison, that's about four hundred times stronger than the powerful magnets used in today's MRI machines in hospitals, and tens of millions of times stronger than the Earth's magnetic field.

Although a stronger field has been achieved before, this has been done in outdoor experiments using explosives. Successfully generating and controlling such a strong field in a room could open up new frontiers in semiconductor physics. Perhaps this will allow scientists to achieve the so-called quantum boundary, that is, a situation where all electrons in a material are limited to the lowest ground state in which exotic quantum phenomena can occur.

The super-strong magnetic field also affects the prospects for nuclear fusion, where high-energy plasmas are driven by magnetism. Scientists believe that magnetic field strengths of 1000 Tesla or more or more may be required to reach the quantum limit or sustain nuclear fusion.
