The magnetic field of an infinite straight wire, distributed over a short 13 distance Δz, is used to approximate the magnetic field at the top of a wire coil. Here, we extend Gao''s method to account for a monoenergetic proton beam passing through electric and magnetic fields corresponding to a charged, current-carrying straight wire.
