A Comprehensive Selection Guide About Industrial Magnets

Industrial magnets have different ranges of applications in the present market condition. They are a great invention but are more than just toys. These magnets come in different shapes, sizes and classifications. You can buy them in small sizes, large and long sizes. Since they serve a larger purpose, they are suited for everyday usage. It is heavily utilised in the oil rigging and construction sites, coal mining industry etc.

Types of Industrial Magnets

The manufacturing of industrial magnets is solely for industrial use only. They include bulk magnet material, magnetic assemblies, magnetic lifts, sweepers, sheet handlers, retrievers and permanent electromagnetic combinations.

Classifications of the Magnet

The permanent magnet varieties always exhibit an outstanding magnetic property. The manufactures designate it with an MMPA class, also known by the name of Magnetic Materials Producers Association. Each of these addresses the relevant characteristics and properties, the specifications of the material, and the established subgrades.
The commonly recognisable sub grade descriptions are often referenced like Alcino 1,2, Ceramic 5,8 etc. This brief designation is a classification of every subgrade measured by the normal energy product and the coercive force that is typically intrinsic.

Specifications of the Magnet

Common materials utilised to make industrial magnets include the following –

  1. Neodymium Iron Boron or NdFeB
  2. Samarium Cobalt or SmCo,
  3. Ferrite or Ceramic
  4. Aluminum-Nickel-Cobalt or AlNiCo
  5. Iron-Chromium-Cobalt.

Physical Forms

The magnet is available in different forms and shapes.

  • Blocks or bars 
  • Strips and sheets that are flexible  
  • Rod  
  • Powder magnets 
  • Sheet or slabs 
  • U-shaped or horseshoe shape
  • Round rings or disc-shaped Round, ring or disc
  • Sphere or bead
  • Arc segments 
  • Buttons or pot
  • Poles or Rotor


The industrial magnet varieties can be in the non-magnetised form. You can get it with conventional or multiple magnetisations too. You can magnetise the non-magnetised magnet after assembling it in the magnetic circuit. The conventional magnet will have one pole on every side, one on the south pole and the other on the north.
You can magnetise it through its thickness, diameter and length. Some magnets come with multiple magnetisations with multiple poles on every side. On each surface, you can find two or more sets of poles. The north and south poles alternate through the material thickness. It is also important to consider the number of poles on each magnet face.
