Product details

  • SKU 10040
  • Pull Force*

    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

Uses for our ferrite disc magnets:

The scope of work for medical research facilities usually begins in the laboratory and then extends to wide-scale community studies with a focus on diagnosis, prevention and treatment of disease or disorders of the mind and body. These steel capped 20mm x 3mm ferrite disc magnets are sprinkled throughout the laboratory equipment medical research facilities rely on to discover the behaviours of pathogens. These ferrite disc magnets can be found in electronics and electrical equipment in laboratories to reliably regulate the moving parts within. Magnetic engagement can also be found as a method of fixing or joining cabinetry, climate and temperature controlled units, shelving and benchtops.

This method of securing components of the laboratory infrastructure with magnetism allows for ease of deconstruction for cleaning, sterilising or resurfacing of all surfaces in order to better control potential contaminants.

Disc magnets, including steel capped ferrite disc magnets, deployed as opening and closing protocols hold by ‘bond’ rather than ‘tie’. That is, they engage two surfaces by magnetic pull force. Similarly, magnets release at a known pull force to allow draws and doors and cabinets to open.

By engaging and releasing moving parts with magnetic bond, surfaces or component parts are not pierced or breached. This method is a technique of designing out voids or breaches of the surfaces and infrastructure of the laboratory where otherwise moisture, bacteria and viruses might hide and prosper.

Ease of deconstruction of any and all surfaces in the laboratory makes possible more regular and thorough cleaning and sterilising. Ease of deconstruction and reconstruction makes this necessary process more economical and provides comfort that laboratory infrastructure can be more easily discounted as a culprit in any contamination event. In the never ending campaign against disease, magnets, like these ferrite disc magnets have joined the battle.

Some applications for our Ferrite magnets are handcrafts, souvenirs and fridge magnets.
