Earth Magnetosphere Charged-Particle Trajectory Mapping
View in 3D how a charged particle will navigate through the Earth's magnetic field!

This project calculates positively or negatively charged particle trajectories
through the magnetosphere for different Kp indexes
and outputs a VRML(*.wrl) 3d plot of the particle trajectory
