You're stuck trying to increase the flux density, because magnets,
for best efficiency and stability, already run the gaps at or near
the saturation flux density at the gap, limiting the flux density
practically to 1 Tesla (10 kGauss). Adding more magnet will only
waste material: 10 kGauss is the limit.


Damn, nobody told Lowther............... :-)
