The maximum theoretical field strength for a neutron star, and therefore for any known phenomenon is 1013 T. Why is there a maximum?

Tide, could you explain that please?
Ah yes, thank you very much.Tide said:Magnetic fields arise from the flow of current or the intrinsic magnetic moment of a spinning particle (which is essentially a current). The speed of light limits the flow of current and charge is invariant under Einstein-Lorentz transformation. Assuming finite charge density, magnetic fields due to electrical current are therefore bounded by the speed of light.

I'm not sure what you mean by "maintain" since the magnetic moment is a permanent property of the atom.

SESSION 7: SPECIAL SESSION: ELECTROSTATIC CONSIDERATIONS IN INDUSTRY
MODERATOR: D. Swenson, 3M
7.7 CASE STUDY - LARGE PLASTIC WEB ELECTROSTATIC PROBLEMS, RESULTS AND CURE,
D. Swenson, 3M Company
Tremendous static charge generation on a plastic web causes unique physical phenomena and special problems. Solution was simple and cost effective.
David Swenson of 3M Corporation describes an anomaly where workers encountered a strange "invisible wall" in the area under a fast-moving sheet of electrically charged polypropelene film in a factory. This "invisible wall" was strong enough to prevent humans from passing through. A person near this "wall" was unable to turn, and so had to walk backwards to retreat from it.
That's a fascinating quote, Moo. I don't have time to check the link right now, but am looking forward to it later.
