What is the surface magnetism range of N52 neodymium magnets?

 N52 magnets are currently one of the highest-performance grades of commercially available neodymium-iron-boron magnets. They offer the advantages of compact size and strong magnetic pull, making them highly popular among customers across various industries. Some users are curious about the range of surface magnetism (surface magnetic field strength) for N52 magnets; I hope my response below will be helpful to you.

What is the range of surface magnetic field strength for N52 magnets?

For N52 magnets, the magnetic field strength typically ranges from 1,200 to 5,600 gauss, depending on the magnet’s size, shape, and measurement location. Generally, smaller N52 magnets have higher surface magnetic field strengths because they are smaller and their magnetic fields are more concentrated. Larger magnets, on the other hand, may have relatively lower magnetic field strengths per unit area due to their larger surface area.

For example, a small, thin, 2 mm × 0.3 mm N52 circular magnet has a surface magnetic flux density of approximately 1,400 gauss, while a 30 mm × 30 mm N52 neodymium cylindrical magnet can have an apparent magnetic force of up to 5,500 gauss.

If you want to determine the gauss value of an N52 magnet, you can use a gauss meter to measure it. When taking measurements, pay attention to the measurement distance and direction; the gauss meter’s sensor probe must be parallel to the magnet, and the measurement direction must align with the magnet’s direction of magnetization.

Notes:

Surface magnetic flux density data does not directly reflect the magnet’s overall magnetic performance; rather, it is closely related to its geometric shape.

If a higher surface magnetic flux density is required, this can be achieved by increasing the magnet’s thickness and upgrading the performance grade (e.g., N54).
