If the reason the objects are sticking to the "magnetic" person is because of magnetism instead of simple skinfriction, 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。

Measured Q-S curve are back figured by nonlinear optimization approach and model parameters are found simultaneously, then distribution of axial force and skinfriction along pile are calculated.
