RingDiskTools is a handy for quick electro-magnetics checks without heavy math. Get the electric potential and field along the axis of a charged ring to size forces and tune setups. Find the potential and field from a flat, evenly charged disk to plan spacing, shielding, and sensor spots. Estimate the stored energy of a charged ring so your supply has safe headroom. Roughly gauge a disk’s capacitance from its size and gap during early design picks. Compute the magnetic field on the axis of a current loop for coils, probes, and fixtures. Check magnetic scalar potential on-axis to compare field shapes and stack loops wisely. Add up results from many rings or disks on one line to shape custom field fast.
