Overview
This macro will create a ring coil with ferrite core based on user input.
 

 Once the ring coil has been created, only a wire port and a voltage source need to be created. A near field request already exists. VEP is used for the ferrite core.
 A video to demonstrate the workflow is attached.
Usage/Installation Instructions
- Open ring_coil_macro.lua in CADFEKO's Script Editor
  - Run the script, enter vaules as wished
  - Add wire port and voltage source
  - Run solver
