Abstract
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.

الملخص
في هذا البحث، سيتم دراسة ديناميكا حركة الكترون متحرك في مجال مغناطيسي. سيُرى ان الدفع الزاوي يلعب دوراً هاماً في تحديد التغير في سرعة الالكترون عند النظر في ديناميكا الحركة في حالتين: في الحالة الأولى، سيرى ان الالكترون سيترك مداره بسرعة تساوي نصف سرعته الابتدائية في المدار عندما يتناقص المجال المغناطيسي الى الصفر. أما في الحالة الثانية، فسيرى أن سرعة الالكترون النهائية في المدار، عند دخوله مجال مغناطيسي عمودي على اتجاه سرعته الابتدائية، تساوي ضعف سرعته الابتدائية قبل دخوله للمجال المغناطيسي. إن المعالجة الحالية تعمق فهم ديناميكا الحركة في الأنظمة الكهرومغناطيسية.
