Neodymium Block Magnets

The obscure metric dimensions of this rectangular rare earth magnet substitute exactly with the commonly used U.S. Imperial measurements of 2x1/2x1/4 inches Wide, long Neodymium magnets are sometimes glued into a steel channel with similar but slightly larger dimensions that, in a similar way to Neodymium Pot Magnet assemblies, protects the brittle Neodymium magnet from impact damage while simultaneously increasing its holding strength.This enhancement of magnetic power occurs because one of the poles is deflected downward by the steel casing which then amplifies the magnetic field at the uncovered base. Long, thin rectangular magnets are ideal for incorporation into magnetic assemblies and implements that can then be used for metal collection, holding, clamping, metal detection and metal decontamination purposes. In many cases the steel channel is drilled with holes so the magnetic apparatus can be screwed neatly into position without damaging the brittle magnet inside.This type of assembly is the basis of most wall-mounted knife and tool holding devices. Large pole areas located along the entire length dimension of these thin rare earth magnets mean that aligning the magnet with an opposing metal surface or metal striker is easier and requires less accuracy and less time to perform. This can be useful in holding magnetic fly screen flaps together or to make sure curtains or canvas covers align correctly and quickly.
