Length/Width 21mm - 30mm

AMF Magnets is the market leader in providing high quality magnets to the Australian market. Our range is large and diverse, reflecting the needs of our valued customers. To assist our customers in finding the right magnet for their application we have created a number of categories including this size based category. Each of the over 50 items in this category have a length or width dimension of between 21mm and 30mm.

Length/Width 21mm - 30mm

Using the filters on the left side of the page allows you to narrow down the number of results so that they best reflect what you are after. The shape of the magnet is often an important component of the purchasing decision. Here you will find a number of block magnets, magnetic tape and magnet strips along with a few other options. Ferrite magnets, separator bars and flexible magnets seem to be well represented in this size range.

Ferrite magnets

Ferrite magnets have a dull dark grey appearance and are frequently used as fridge magnets, education magnets and whiteboard magnets. They are weaker than Neodymium magnets and require a larger magnet to achieve a comparable hold. However this also means they are easier to handle as fingers are able to gain greater purchase in order to move or remove a magnet. Their larger size also makes them safer in education settings. Small Neodymium magnets can pose a serious risk to people if ingested, making them inappropriate for children to handle.

Separator bars and separator tubes

For many industries heavy duty magnetic equipment are essential operating tools. Magnetic separator bars, magnetic tubes, magnetic grate assemblies and plate magnets are all core components of all sorts of material processing equipment. They work by attracting ferrous materials to them, preventing them from continuing through the mechanical workings of the processing system. Ferrous contaminants come in a number of forms, including microscopic powders that are part of the material being processed or larger metal debris picked up during the harvest.
Ferrous materials are not only a nuisance, they can also be a real hazard. Magnetic filter bars are able to remove the metal contaminants, preventing them from causing damage to equipment or contaminating goods.

Flexible tape

Magnafix and NeoFlex are two of the branded products we supply. Magnafix has been developed as a strong and reliable two part magnetic attachment system. This means the product is designed so that part A magnetic tape is applied to one surface and part B tape to another. They are matched so that the two tapes align perfectly when in use. This perfect for many signage and advertising displays that are temporary but need a safe and reliable hold whilst in place.

NeoFlex on the other hand is Neodymium based flexible material that comes in rectangular sheets and as magnetic tape. NeoFlex is incredibly powerful and is a durable and handy way of achieving a magnetic hold. Simply use the adhesive backing to attach it to a nonferrous material. This is then ready to use as a magnet on any steel or iron surface. You can cut the tape to size using scissors or a craft knife. This flexibility means you can simply add or remove some of the tape to achieve the exact hold you desire. Magnetic tapes are a great solution for many situations that require a low profile magnet.

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
