Of course it's totally useless - but if you needed to attach a pile of 50 sheets of A4 paper (80g/m2) to a metal cabinet - you could.
Uster - 21:00- And my magnet is still holding!
The disc magnet S-20-10-N (20x10 mm) can hold approximately 1.75 kg in shear direction, then the steel plate starts sliding down.
If you place a rubber tape between magnet and steel plate, the disc magnet can hold approximately 5.2 kg in shear force; then it starts to slide down.
With a self-adhesive silicone disc between magnet and steel plate (invisible because it has the same diameter as the disc and is only 0.5 mm thin) the disc magnet can hold over 5 kg in shear direction; then it starts to slide down.
