[ExI] Super powerful 42 Tesla magnet that uses less than one watt

[John Clark]

*The most powerful artificially produced constant magnetic field ever made
was at the National High Magnetic Field Laboratory in Florida; it had a
strength of 45.5 tesla and required 20 million watts of electricity to
operate. But the March 13, 2026 issue of the Journal Science Advances
reports on the construction of a magnet that is almost as strong, 42 tesla,
that needs less than one watt of power to operate!  This could lead to big
improvements in MRI imaging machines, particle accelerators, and fusion
power reactors. And it could lead to a better scientific understanding of
how super powerful magnetic fields behave. *
