200kg - 500kg

Most of the rare earth magnets in this 100-200kg strength category are only suitable for Commercial, Scientific and Industrial operations. Applications that use these powerful magnets must be strictly monitored and supervised by qualified and experienced operations managers. Strong magnets like these large neodymium magnets have the potential to cause severe injury if mishandled or when used incorrectly. Large rare earth magnets should never be handled without the appropriate PPE and only by experienced professionals.

The super strong Holding Pot Magnets in this category are useful for metal retrieval, decontamination and Magnetic Fishing. These extremely durable steel encased magnets are used by AMF customers in rural and outdoor environments. Discarded metal waste like nails, nuts, bolts and wire can be problematic for the health of farm animals. Contamination of this nature is also an issue in the production and distribution of quality of food crops.

Fishing Magnets are used by farmers who want to recover metal fencing wire and alike. They are also used by mining exploration companies to retrieve broken metal casings and drill bits from deep boreholes.

Other customers engage in Magnetic Fishing and use these retrieval magnets to explore underwater environments such as dams, ponds and rivers. Unsurprisingly a lot of heavy ferrous metal material can be found at the bottom of these waterways.

By retrieving the metal objects contamination levels are reduced and waterways can be environmentally remediated. In some cases, valuable metal objects can also be found. Other magnetic items related to commercial applications can be found in the Warehouse and Industrial magnet category.

Powerful magnets are important for Scientific and Medical Research.

Very large permanent magnets have the ability to influence the behaviour of electrons spinning around the nucleus of atoms in the human body. Large Permanent magnets in low-frequency medical MRI machines create the environment to detect anomalies in human tissue. They achieve great accuracy, at a lower power cost than electromagnetic machines. This in turn enhances the quality of the associated high resonance images. Furthermore the diagnostic capabilities of the health professionals who operate them is also enhanced.

Permanent magnets help deliver these images without the need for potentially dangerous radiation. Unlike other diagnostic methods, MRI machines can be repeatedly used to monitor patient health with far fewer side effects. MRI imaging helps to deliver oncology medicine in a more accurate and less invasive fashion. Repeated monitoring of cancerous tumours is safer and much easier to perform.

Rare Earth magnets of considerable size also play an important role in Aerospace projects. They can be used to imitate attractional forces that are absent in zero gravity space environments. Permanent magnets do not draw on electrical power sources to operate. This is also extremely important for high-tech battery or solar-powered technologies.


Best uses for magnets with 200kg-500kg pull force?

Magnets with this type of extreme holding power are mostly found in commercial operations. These industrial operations include mine sites, construction sites, fabrication shops, shipyards and manufacturing plants. Large Pot Magnets like the Fishing Magnets in this category are especially useful. Popular for use in industrial metal clamping, lifting and retrieval applications where their superior Neodymium strength can be harnessed.

Many modern technologies are moving to include magnetic power in the operation of electrical systems, safety and warning systems, and renewable energy systems. The use of Neodymium magnets in these technologies has led to systems and operations that are more reliable and efficient. They also support these systems to be less dependent on finite fossil fuel resources.

The reliable and independent nature of rare earth magnets is also highly valued by risk-averse sectors like the Military and Aviation industries. Each of the products in this 200-500kg category qualify for free standard shipping Australia wide.

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
