Yes, I meant MAGNETIC. It's called Lorentz Force Turning. A charged object moving through a magnetic field experiences a force at right angles ti its direction of motion and the magnetic field. The magnitude of the force is described by the equation: |Fbar| = |QVbar * Bbar| = QVBsin theta where Q is the charge on the object, Bbar is the magnetic field vector, Vbar is the velocity vector, and theta is the angle between Vbar and Bbar. Skipping a bit of math involving the application of Newton's Second Law, this can be reduced to: r = mV/QB where r is the radius of the orbit, m is the object's mass. Hope this helps <G> Lee
