700 5 16. 4. If all the line integrals were path independent then it would be impossible to accelerate elementary particles in places like CERN. After all, then the work done by the field on the particle travelling a full circle would be the same as if the particle not travelled at all. That is, zero.

S2E: Solenoidal Focusing The field of an ideal magnetic solenoid is invariant under transverse rotations about it's axis of symmetry (z) can be expanded in terms of the on­axis field as as: See Appendix D or Reiser, Theory and Design of Charged Particle Beams, Sec. 3.3.1 4.6: Gradient, Divergence, Curl, and Laplacian. In this final section we will establish some relationships between the gradient, divergence and curl, and we will also introduce a new quantity called the Laplacian. We will then show how to write these quantities in cylindrical and spherical coordinates.16 abr 2020 ... ... field because it does not produce a great enough solenoidal velocity component to amplify the magnetic field.

Assuming that by "ideal coil" you refer to a purely inductive coil with an ohmic resistance R = 0, you can assume that, for the purposes of calculating total resistance, the coil is simply a short-circuit that bypasses the resistor in parallel.
