Path: CubeSat/Damping
% Magnetic hysteresis over multiple orbits. Shows the magnetic field in a magnetic hysteresis damper over multiple orbits. The goal is to verify that appropriate hysteresis curves are seen in the computed bar flux. Without external torque, there will be one hysteresis loop per orbit. When using the hysteresis function you must be very careful to have the field rate in the body frame. Otherwise the magnet can go past saturation. In addition, use BFromHHysteresis to set the initial value for the b field in the bar. Things to try: 1. Try different bar orientations in the body frame 2. Different orbits and initial rates 3. Try different numbers of points per orbit. 4. Add a nonzero torque See also BFromHHysteresis, MagneticHysteresis, BDipole, RVFromKepler, FRB, RK4 ---------------------------------------------------------------------- % -------------------------------------------------------------------------- Copyright (c) 2014 Princeton Satellite Systems, Inc.
