You need lotsa' gauss in a largish air gap for proper quench and thus this
method is best used on smaller systems as a concept demonstration.  The
newer Ne:Fe:B magnets are far too heat sensitive to use near hot gap
structures as they reach their curie point at very low temperature levels.
Ferrite is a bit too weak and alnico a bit too expensive for assembling a
really large and effective magnetic quench gaps system for a giant system.
