This ferrite block magnet has a 50mm length, a 19mm width and a height of 4.9mm. This ferrite magnet has a magnetic flux reading of 1244 Gauss and a pull force of approx 500 grams. It is identified by the AMF magnet part number 12041.
Smaller ferrite block magnets like this item are lightweight, inexpensive and extremely resistant to corrosive forces. They are able to withstand harsh outdoor environments and are often used in sensors and alarms but are also popular for use in handicrafts and hobbies. All Ferrite magnets have excellent heat and corrosion resistance but are relatively low in pull force and mechanical strength, which makes them susceptible to cracking and breakage.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
