1. Решение

Для определения направления магнитных линий, создаваемых током в проводнике, используется правило буравчика, также известное как правило правой руки. Правило гласит: если направить большой палец правой руки по направлению тока в проводнике, то четыре согнутых пальца, обхватывающие проводник, укажут направление линий магнитного поля. Эти линии представляют собой замкнутые окружности, лежащие в плоскостях, перпендикулярных проводнику.

В соответствии с направлением стрелок на исходном рисунке, электрический ток втекает в правый вывод, движется по прямоугольному контуру по часовой стрелке и вытекает из левого вывода. Применим правило правой руки для каждой из четырёх сторон прямоугольника:

  • Правая сторона: Ток направлен вверх. Располагаем правую руку так, чтобы большой палец указывал вверх. Согнутые пальцы покажут, что магнитные линии огибают проводник против часовой стрелки (если смотреть на проводник сверху). Внутри контура поле будет направлено «от нас» (в плоскость рисунка), а снаружи — «к нам».
  • Верхняя сторона: Ток направлен влево. Большой палец направляем влево. Согнутые пальцы покажут, что магнитные линии огибают проводник против часовой стрелки (если смотреть на проводник слева). Внутри контура поле также будет направлено «от нас».
  • Левая сторона: Ток направлен вниз. Большой палец направляем вниз. Согнутые пальцы покажут, что магнитные линии огибают проводник по часовой стрелке (если смотреть на проводник снизу). Внутри контура поле снова будет направлено «от нас».
  • Нижняя сторона: Ток направлен вправо. Большой палец направляем вправо. Согнутые пальцы покажут, что магнитные линии огибают проводник по часовой стрелке (если смотреть на проводник справа). Внутри контура поле также направлено «от нас».

Таким образом, магнитные поля от всех четырёх сторон складываются, и внутри контура суммарное магнитное поле направлено перпендикулярно плоскости рисунка, «от нас». На рисунке ниже показан проволочный прямоугольник и по одной магнитной линии для каждой его стороны с указанием направления.

Ответ:

Используя правило буравчика (правило правой руки), определяем направление магнитных линий вокруг каждой стороны прямоугольного контура, по которому течёт ток по часовой стрелке. Магнитные линии представляют собой замкнутые кривые, охватывающие проводник. Направление этих линий показано стрелками на представленном выше рисунке. Для всех сторон контура магнитное поле внутри него направлено одинаково — перпендикулярно плоскости контура, «от нас».
