Frequently Asked Question

  • How can I identify the poles of a magnet?

    There are several simple methods that can be used to identify the strong magnet North and South poles of neodymium magnets. 


        1. The easiest way is to use another magnet that is already marked. The North pole of the         marked magnet will be attracted to the South pole of the unmarked magnet.


        2. If you have a compass handy, the end of the needle that normally points North will be         attracted to the South pole of the neodymium magnet


        3. Use one of our Pole Identifier Devices.



  • What does a magnetic field look like?

    The traditional way of visualizing magnetic fields is to place a magnet near a surface covered with iron filings.

  • Can you supply BH Curves, or Demagnetization Curves for your magnets?
    Yes, we've posted Demagnetization Curves for our most common Neodymium magnet grades right here.
  • Will a magnet with a 20 lb pull force lift a 20 lb object?
    Because pull force values are tested under laboratory conditions, you probably won't achieve the same holding force under real world conditions. The effective pull force is reduced by uneven contact with the metal surface, pulling in a direction that is not perpendicular to the steel, attaching to metal that is thinner than ideal, surface coatings, and other factors.
  • How is the strength of a magnet measured?
    The strength test of NdFeB magnets by lot of professional testing instruments, such as tensiometer, flux meter, Gauss meter, etc. And AIM Magnet has those instruments to ensure high quality magnets have provide to customers.
  • What materials do magnets attract?
    Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals.
  • What does "Magnetized thru thickness" mean?

    We use "Magnetized thru thickness" to indicate pole locations on our block magnets. The thickness is the last dimension listed, with poles on the top and bottom when placed vertically.


    Of course, we can also provide a variety of magnetizing directions.


  • Does stacking magnets together make them stronger?
    Yes, the strength of the magnet will be increased because stacking multiple magnets into one larger magnet exerts greater magnetic properties. As more magnets are stacked together, the strength will increase until the length of the stack equals the diameter.
  • Can you supply monopole magnets?
    No, we don't, nor does anyone else, because they don't exist. All Neodymium magnets must have at least two poles.
  • Can I solder or weld to neodymium magnets?
    You definitely cannot solder or weld to neodymium magnets. The heat will demagnetize the magnet and could cause it to catch fire posing a safety risk.
