Electrons emitted with negligible speed from an electron gun are accelerated through a potential difference V along the x-axis. These electrons emerge from a narrow hole into a uniform magnetic field B directed along this axis. However. Some of the electrons emerging from the hole make slightly divergent angles as shown in fig., show that these paraxial electrons are refocused on the x-axis at a distance sqrt(8pi^2 mV)/sqrt(eB^2) .
