Magnetostatic Field Calculations Associated with Thick Solenoids in the Presence of Iron

摘要

The effect of iron on the uniformity of the field produced by an axisymmetric thick solenoid is considered. Using a power series expansion of the vector potential in the radial and axial coordinates the potential is found and from this the magnetic induction B is derived. The solution to the vector potential and field components is also obtained using a Maclaurin series expansion in terms of the radial coordinate, ρ with numerical results using both methods of solution computed.
