Path: SC/MagneticControl
% Simulate the attitude of a rigid spacecraft with permanent magnet in LEO Demonstrates how the magnet dipole aligns with the Earth magnetic field over time. Depending on the orbit inclination and altitude, the field strength and direction undergoes a periodic change throughout the orbit. The magnetic field varies at twice orbit rate as shown in the plot. The resulting motion is an undamped oscillation. The natural frequency of the oscillation changes with the square root of the inertia. The simulation includes gravity gradient torque as well.
