Magnetic solenoid for generating a substantially uniform magnetic field

摘要

One embodiment of the invention includes a magnetic solenoid. The magnetic solenoid includes an elongated sidewall that extends between spaced apart ends. The elongated sidewall can surround a central axis that extends longitudinally along the sidewall. The elongated sidewall can have a radius that is defined by a compound equation that varies the radius as a function of position along the central axis.
