High B-Field Low Inductance Comsol Study and Coil Design

Player Skill in Connect Four

Research and development of a coil able to produce a high magnetic field with the lowest possible inductance in order to facilitate high speed high voltage magnetic pulses into an external media.

Explore

The purpose of this work was to research the magnetics in several coil designs, do a complete B-field versus inductance study, a comprehensive state of the art review, and use the results to develop a high B-field low inductance coil to replace the contracting companies current high energy pulsing coil. The ultimate coil was used to further the contracting companies research which is covered by NDA.

This project was broken up into three parts. First, a study in the current state of the art and a deep dive into the mathmatics via Matlab. Second, a set of designs in COMSOL based on the best found solutions in the former study. Third, a physical coil created based on the best of the COMSOL designs. Seen here are project deliverables.

Numerous designs with numerous iterations were designed and simulated to find the best fit for the application. While the design goals were to maximize B-Field and minimize inductance, specific physical restraints limited the ultimate final product choice.

A final design was chosen and run through all simulation aspects to determine the best final specs. The design was then manufactured alongside a housing to match the product placement.
