Repo for work done on Waterloop's Halbach Wheels

main.py

Plots the lift force and the drag force on a Force vs RPM graph.

Assumptions

• Diameter of Wheel = 10"
• Spacing between Magnets = 0.5"
• Number of Magnets in each wheel = 20 (5 halbach sets of 4 magnets each)
• Magnetization of each Magnet = 796kA/m (using Hcb value of N52 Neodymium Magnets from here)
• Thickness of beam = 15mm
• Distance from beam = 10mm
