Почему колебание стрелки компаса быстрее затухает, если компас прибора латунный и медленнее, если корпус прибора пластмассовый?

Объяснение:

Металлический корпус является замкнутым контуром для токов, наведённых колебаниями магнитного поля стрелки, и токи этого контура создают своё магнитное поле, "успокаивающее" стрелку. Чего нет в пластмассовом корпусе.
