Здравствуйте! У меня возникли сложности с таким вопросом:
Электрон с энергией 2 МэВ движется прямолинейно. Найти максимальное значение индукции магнитного поля, создаваемого электроном на расстоянии 10 см от его траектории.

Здравствуйте, masha215!
Я думаю, что задачу можно решить так.
Кл - заряд электрона,
кг - масса электрона,
- скорость электрона,
Дж - энергия электрона,
м - расстояние от траектории электрона до точки, в которой нужно вычислить максимальное значение индукции магнитного поля,
Ф/м - электрическая постоянная,
м/с2 - скорость распространения электромагнитных волн в вакууме.
Из формулы для энергии
электрона
после преобразований получим
то есть электрон является релятивистским.
Напряжённость электрического поля движущегося электрона имеет максимальное по абсолютной величине значение
под прямым углом к направлению движения, равное
Учитывая, что
получим для максимального по абсолютной величине значения индукции магнитного поля движущегося электрона
и в нашем случае
(Тл).
