Creating a Uniform Magnetic Field for Penning Traps without Electromagnets

[lamonster]

i understand that a penning trap needs a uniform B field and an electric field to confine charged particles, but how would one make a uniform magnetic field that doesn't use electromagnets?

Why couldn't you use electromagnets? They use them on Helmholtz coils: http://en.wikipedia.org/wiki/Helmholtz_coil

Ive never said this to a stranger, but I love you. That solved my problem exactly.
