Yp Force Magnetique

YP Force Magnetique is the french version of YP Magnetic Force. 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.
