Magnetic strength can be multiplied by up to 32 times by using steel armatures to concentrate magnetic flux. Such armatures may take the form of backing plates, channels or cups. The maximum increase in power is obtained when magnets are sandwiched between two plates.

For example: A 0.187" thick x 0.750" wide x 1" long rubber magnet has 4 oz. of pull strength. The same magnet bonded to a channel (assembly #RMCH-10) will pull 5 Ibs., which is 20 times greater. Furthermore, the same magnet sandwiched between two plates (assembly #RMSA-10) will pull 8 Ibs.—32 times more than the magnet alone!

Many of these assemblies use ceramic magnets which may break if dropped or mishandled. Please handle with care.

Pull force is tested on a flat steel ground plate 1/2" thick. Thinner, coated, rusted or rough surfaces on the Steel will reduce the amount of pull force.
Other sizes and finishes can be manufactured to your specifications. All round bases and some channels and sandwiches are available in a tough, black powder coat finish. Black vinyl coating is also available if your application should require it.
