Motion of a charge in a uniform magnetic field

A proton (positive charge, red) and an anti-proton (negative charge, blue) move in a magnetic field B = 10-3 T i.  At t = 0 both particles are at x = y = z = 0.  You can choose the initial velocity components of the particles in units of 103 m/s.  The tick marks on the axes are spaced in units of cm, and at a screen refresh rate of 60 Hz one second of real time represents ~ 0 microseconds of animation time.
