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.

There are several ways to create a uniform magnetic field for Penning traps without using electromagnets. One method is to use permanent magnets arranged in a specific configuration to produce a uniform field. Another approach is to use superconducting coils, which can produce a strong and uniform magnetic field without the need for electrical current. Additionally, some materials such as mu-metal can be used to shape and direct magnetic fields, allowing for the creation of a uniform field without the use of electromagnets. Another option is to use a Helmholtz coil configuration, which consists of two identical circular coils placed parallel to each other and connected in series to produce a uniform magnetic field at the center. Overall, there are various techniques and materials that can be utilized to create a uniform magnetic field for Penning traps without the use of electromagnets.
