Magnetic Hair for Wall Mobility

We introduce a climbing system, inspired by gecko foot that uses magnets in place of Van der Waals interaction. This is possible because both forces, except for a scale factor, have similar force-curves. Taking advantage of this fact, we manufactured a hand-size "magnetic" version of a gecko-foot. This allowed us to conduct naked-eye experiments. As a result we identify four shape function relations that might partially explain the design of gecko feet. Additionally, we report experimental data, introduce a quantitative concept to compare climbing systems and show a prototype of magnetic hair
