162. Как будет взаимодействовать магнит с проволочным витком с током (рис. 16, а) — притягиваться или отталкиваться?
Рис. 16
Решение. №162 (с. 281)
Решение
Чтобы определить, как будут взаимодействовать магнит и виток с током, необходимо сначала определить магнитные полюса, которые создает виток. Любой проводник с током создает вокруг себя магнитное поле, а замкнутый виток с током ведет себя подобно плоскому магниту, имея северный (N) и южный (S) полюса.
Для определения направления магнитного поля витка и, соответственно, расположения его полюсов, используется правило правой руки (или правило буравчика). Согласно этому правилу, если обхватить виток ладонью правой руки так, чтобы четыре пальца были направлены по направлению тока, то отставленный большой палец покажет направление линий магнитной индукции $ \vec{B} $ внутри витка. Линии магнитной индукции всегда выходят из северного полюса магнита и входят в южный. Следовательно, сторона витка, откуда выходит вектор магнитной индукции $ \vec{B} $, является его северным полюсом (N).
Рассмотрим случай, представленный на рисунке 16, а). Ток в витке направлен против часовой стрелки, если смотреть со стороны постоянного магнита. Применяя правило правой руки к витку, мысленно направляем пальцы по току. Большой палец при этом будет указывать вправо, в сторону магнита. Это означает, что сторона витка, которая обращена к магниту, является северным полюсом (N), а обратная сторона — южным полюсом (S).
Постоянный магнит расположен так, что к витку обращен его южный полюс (S).
Взаимодействие между магнитами подчиняется простому правилу: разноименные полюса (N и S) притягиваются, а одноименные (N и N, или S и S) отталкиваются.
В данном случае северный полюс (N) витка с током находится напротив южного полюса (S) постоянного магнита. Следовательно, между витком и магнитом возникнет сила притяжения.
Ответ:
Магнит и проволочный виток с током будут притягиваться.
