Unipolar Radial Oriented Magnetized Ring Magnets D21x15x15mm

<p><strong>High performance</strong>: The sintered NdFeB radial ring magnet is molded by radiation orientation technology. After magnetization, each magnetic field line points to the center of the circle and is evenly distributed. The advantages of being mounted on the motor are high control accuracy, large speed regulation range, good dynamic balance, low temperature rise, small cogging torque, high efficiency, low noise, and easy assembly.</p>

<p><strong>Perfect Coating Available</strong>: Ni Cu Ni Triple Layer Coated for maximum durability and protection against corrosion.Shinny and High temperature resistance.</p>

<p><strong>Great Magnetic Grade</strong>: Rare earth permanent Ndfeb radiant ring magnet with an incredible Grade N38 Magnetic Energy, stronger than N35, and a whopping 10x Stronger than the strongest ceramic magnet. The surface gauss arrives to be 3000 gauss.</p>

<p><strong>Widely Use</strong>: Use the radially oriented ring magnet for just about anything, including science experiment, various projects &amp; presentations, education, DIY Projects and Much More.</p>

<p><strong>High Accuracy</strong>: The magnets are produced by professional Nefeb <a href="radial-ring-magnets-c-19.html">radial ring magnets</a> factory. All Tolerances are +/-0.002". We can produce other sizes radial ring magnets with Sintered or Bonded Ndfeb Magnets.</p>
