The CERN large hadron collider LHC (2017) describes a hadron (proton) beam that is accelerated using a superconducting coil but a magnetic field does not accelerate protons. Using an analogy, a solenoid's wire coil that accelerates an iron armature cannot be used to justify the acceleration of protons since a magnetic field of a solenoid produces an affect on metals such as a carpenter nail, paper clip or iron filings. The cyclotron (fig 18) is used to justify the acceleration of the hadron beam but the cyclotron accelerates ions not protons and the accelerated cyclotron ions are accelerated using an electric field produced by two gaps between the two halves of the cyclotron not by a wire coil's magnetic field.
