Neodymium Block Magnet – 70mm X 70mm X 12.7mm

Magnetic Product Description:

This block magnet is 70mm square with a height of 12.7mm or the old imperial equivalent of half an inch. It is classified under the AMF magnet part number 22001B and has a pull force of 63.5kg against 5 mm mild steel. This magnet has a magnetic flux of 1954.

Uses for our rare earth block magnets:

These bold, nickel coated, square neodymium blocks are often used in manufacturing situations for attracting, capturing, removing and storing ferrous material (metal scraps) which often presents a health hazard or a threat to sensitive processing machinery.

One example of this is the decontamination of bulk quantities of loose foodstuffs like grains, pulses and powders during processing. These goods, which are unaffected by magnetic force, are conveyed past magnetic blocks like these as a screening protocol. This simple, non-contact method rids and purifies these valuable foodstuffs of ferrous material like nails, screws, washers, flakes of rust and the like. Scraps of metal can turn up in the most surprising and alarming places, largely because of the indestructible nature of metals.

From paddock to plate, most foodstuffs are grown, harvested, transported and processed using steel machines and vessels made of metal. Protocols for screening out metal fragments are imposed at reasonable intervals in the production chain as an act of due diligence.

Metal fragments are long lasting and must not be allowed to enter human or other animal bodies. Metal fragments are sharp and strong, easily able to damage or destroy specialised processing machines which can mean shutting down production lines and necessitating mechanical or electrical repairs.

These neodymium block magnets, the strongest type of permanent magnets commercially available, need to be treated with caution. Able to lift thousands of times their own weight, they can strike at each other with enough force to create flying chips that can cause injury or jump toward ferrous materials they attract to.

Ideal for metal separation, industrial, construction, mining and commercial applications where a square shaped magnet is needed. The half-inch thickness is also ideal where an imperial thickness is required.
