Palm-sized magnet rivals world’s most powerful coils for first time, hits 42 tesla
https://interestingengineering.com/science/powerful-miniature-magnet-fits-palm-of-hand"NMR spectroscopy, a powerful method for studying molecular structures, works better with stronger magnetic fields that boost sensitivity and resolution. Right now, using fields above 28 tesla means applying for time at a national lab.
A palm-sized magnet capable of operating in that range — at a fraction of the cost and power — could make high-field NMR far more accessible to university labs and research hospitals that currently can’t justify the expense."
