In this paper, the dynamics of a moving electron in a perpendicular magnetic field region is examined. It is shown that the angular impulse plays an important role in determining the change in the electron's speed when considering the dynamics of motion in two situations. It is shown that, in the first case, the electron will leave its circular orbit with a speed equaling half its orbital initial value when the magnetic field is turned off. In the second situation, the final orbital speed of an electron entering a perpendicular magnetic field is twice its initial speed. The present treatment is suitable for undergraduate students as it deepens their understanding of the dynamics involved in electromagnetic systems.
