Measurement of holding forces

Holding force of permanent magnets to ferromagnetic materials is very often used, especially to iron and its alloys.
Very often the question about holding force of the magnets emerges. It should be emphasized that this force depends on several factors. The first is the actual shape and material of the magnet, in addition to it, also material which is attracted by the magnet, its thickness and surface finish. Holding force changes very significantly with distance from the pad - see chart.

If all conditions are defined, the holding force can be measured using a tensile load cell - see picture.

By default, this power is measured and reported as a parameter to the magnetic holders. It is a magnet with a metal shell, which encloses the magnetic circuit.
The holding force of magnets themselves can be measured on request request, taking into account the fact, that different conditions may vary this parameter.
