YP Magnetic Force is a teaching tool for physics lessons. It simulates the
magnetic force exerted on a particle moving in a magnetic field. The user
can change the electric charge, the velocity and the magnetic field. The
three vectors velocity, magnetic field and magnetic force are displayed in
a three dimensionnal coordinate system which can be rotated in the desired
orientation.
