Bonded Neodymium Ring Magnets
Neodymium Bonded Magnets – Strong Ring Magnets
What is a bonded neodymium magnet? It’s a powerful combination of neodymium magnetic powder mixed with a non-magnetic polymer or rubber binder. The result is a powerful, corrosion resistant neodymium ring magnet that can easily be machined. While they offer less flux, they are easily formed into intricately shaped patterns without suffering any magnetic losses. You can find bonded disc magnets in many applications, including automotive motors, electrical motors, and perhaps even your next project.

What are the characteristics of the magnet?
1) Magnetic flux: Set in a uniform magnetic field with a magnetic flux density of B, there is a plane with an area S and perpendicular to the direction of the magnetic field. The product of the magnetic flux density B and the area S is called the magnetic flux passing through this plane. Referred to as Magnetic Flux. Scalar, symbol "Φ". Simply put: "Use the magnetic field density to measure the strength of the magnetic field"
2) Gauss: is the unit of measurement of magnetic flux, which refers to the number of magnetic lines of force passing through each square centimeter. A Gauss meter is usually used to measure the strength of the magnetic rod.
3) Tesla: It is the derived unit of the international system of magnetic flux density or magnetic induction, usually expressed by T. At the International Metrology Conference held in Paris in 1960, this unit was named in memory of Nikola Tesla, an American Serbian inventor, mechanical engineer, and electrical engineer who made important contributions to the field of electromagnetics. The familiar Tesla cars are named after this Tesla background. The conversion formula of Tesla and Gauss is: 1 Tesla = 10000 Gauss
4) Magnetic Gradient: The rate of change of magnetic field strength or the rate of change of magnetic field density within a unit distance (for example, 1 cm). The degree of inhomogeneity of the magnetic field can be measured by the magnetic field gradient. As shown in the figure below, the distribution of magnetic field lines in a uniform magnetic field is uniform, but the distribution of magnetic field lines in an uneven magnetic field is not uniform. The larger the magnetic gradient, the easier it is to adsorb.
5) Pull Force: The adsorption force of a ferromagnetic object in a magnetic field is usually expressed in kg or Newton as the unit of magnetic force. Usually use a tensile tester to test.
6) Magnet coercive force: Also known as coercivity or coercivity, it is one of the characteristics of magnetic materials and refers to the magnetic field strength required to reduce the magnetization to zero after the magnetic material has been magnetized to magnetic saturation. Coercivity represents the ability of a magnetic material to resist demagnetization. It will be represented by the symbol of HC, and the unit is A/m (international standard system) or Oe (gauss unit system).
The coercivity can be measured with a magnetometer or B-H analyzer (such as FE-2100H permanent magnet material measuring device). If the coercivity is large, it is called hard magnetism and can be used as a permanent magnet material. Permanent magnets can be used in motors, magnetic storage media (such as hard drives, diskettes or tapes), and strong magnetic rods. Ferromagnetic materials with low coercivity are called soft magnetism and can be used in the iron cores of transformers and inductors, and read/write heads of magnetic storage media.
