What is the difference between adhesive force and displacement force-shear force? Or: Why won't my magnet on the wall hold the maximum weight?

The maximum weight that a magnet can hold on a certain surface varies depending on the direction of the application of force.
Our specified adhesive force applies to a holding strength vertical to the contact surface.
If the holding strength acts parallel to the contact surface (shear direction), its maximum value is much smaller (approx. 15-25% of the specified adhesive force).
These values may be improved with the use of special products from our shop and by experimenting with different surfaces.
