A beam of electrons with a velocity of 3.2×10^7 m/s is fired into a uniform magnetic field which has a flux density of 8.5mT. The initial velocity is perpendicular to the field. Explain why the electrons move in a circular orbit. Calculate the radius of the orbit. what must the flux density be adjusted to if the radius of the orbit is desired to be 65mm?
