Due to China reducing the amount of Rare Earth elements being exported out of their
country this new company called Correlated Magnetics Research has come up with new
magnet technologies to stretch the use of rare earth elements and also increase the
holding power of the magnets. See this information below.

Rare-earth multiplier
MaxField™ technology means that your magnetic material can go much further than ever
before. MaxField has demonstrated coupling and shear force improvement in excess of
600% over conventional single dipole magnets. MaxField delivers savings in size, weight,
and materials cost.
