If the reason the objects are sticking to the "magnetic" person is because of magnetism instead of simple skin friction, there's no reason they should only stick to bare skin.
如果东西粘在“磁铁”人身上是因为磁性而不是摩檫力，那么它们只能粘在光秃的皮肤上就毫无道理了。

Some braking systems, such as the Inertial Transfer braking (ITB) system and Dual braking system, make use of both friction and magnetic elements.
有些刹车系统，如惯性转移刹车(itb)系统和双刹车系统，同时利用了摩擦力和磁力的原理。

It is found that the Coulomb friction of the MR fluid damper increases with the increasing of the applied magnetic strength.
