Ещё если вы вдруг раздобыли мощный магнит, попробуйте достать фермагнитную жидкость. Такие жидкости состоят из смеси наночастиц магнетита — минерала, в котором содержится железо, и органического растворителя с добавлением поверхностно-активных веществ.

При воздействии магнитного поля частички самоорганизовываются, ёмкость ближе на поверхности выступили хорошо различимые шипы. Это частицы магнетита выстраивались так под влиянием поля.

Ещё ближе, и жидкость поползла вверх по стенкам ёмкости. Не очень сильно, но всё же она как будто сопротивляется. Да! А теперь попробуйте наклонить ёмкость от себя, почувствуйте разницу.

О да, жидкость явно тянет в одну сторону. Переведено и озвучено студии Верт Дайдер.
