Cylindrical Magnetic Bar

Cylindrical Magnetic Bar

The cylindrical magnetic bar we often use are always rare earth bar magnets, also be called neodymium bar magnets. Seen from the side, it is only a cylinder magnet or cylindrical magnet. As one kind of physical iron remover, Super strong cylindrical magnetic rod, which can be made into long cylindrical magnetic bar or small cylindrical bar magnets for sale, are usually made into different kind of magnetic separators to effectively remove fine iron and a few of 304, little 316 stainless steel weak magnetic impurities mixed in powder, pellet or liquid.

Rare earth permanent magnetic rods adopt the most powerful magnetic circuit design in industry, which can effectively remove the fine iron in material and reduce the material loss. The following simulation diagram shows the distribution of magnetic sensing lines on magnetic rod surface for different magnetic circuit designs, which fully illustrates the correct magnet configuration to the magnetic force influence on magnetic tube surface.

Factors affecting magnetic force

  • Magnetic induction line density on surface of magnet
  • Magnetic field gradient
  • Adsorbed metal particle weight

Characteristics and advantages

  • Standard magnetic rods have a diameter of 25mm
  • The peak strength on the magnetic rod surface is 14000 Gauss
  • Rare earth magnetic circuit design, extreme heat resistance up to 338°F
  • SmCo magnetic system can withstand temperature up to 662°F
  • Surface material 316L cold drawn seamless tube
  • End can be welded handle or cover as a testing tool

Optional configuration

  • Multiple field strength designs to meet different temperature resistance needs
  • The magnetic rods' length can be customized (from 4"to 80")
  • Both ends of the magnetic rod can be plain and sealed, threaded rod, threaded hole or welding handle, etc.


  • Remove iron impurities from liquid piping
  • Used as quality inspection tool for dry powder materials
  • Used in work areas where conventional magnetic grids/grates cannot be installed
  • Material handling

    Plastic pellets, sugar powder, pharmaceutical powders, cheese, rice, grain, food additives, chocolate sauce, jam, etc.
