Why can N35 NdFeB Ring Magnet For Loudspeaker effectively reduce the eddy current loss of magnets in magnetic fields?

The reason why N35 NdFeB Ring Magnet For Loudspeaker can effectively reduce the eddy current loss of magnets in magnetic fields is that the principle behind it involves the geometric design of the magnet and the physical properties of the material itself. The optimization of these two aspects together contributes to this effect.
The design of the ring magnet makes the current path inside it more uniform and smooth. When the magnetic field changes, induced currents will be generated inside the conductor, and these currents will try to offset the changes in the external magnetic field and form eddy currents. The special shape of the ring magnet makes the path of these induced currents smoother and reduces the eddy currents generated by the sudden change of the path. This design helps to reduce the formation of eddy currents, thereby reducing eddy current losses.
The structure of the ring magnet can better constrain the magnetic flux and reduce the leakage of magnetic flux to the outside of the magnet. Magnetic flux leakage is an important source of eddy current loss, because the leaked magnetic flux will generate induced currents in the surrounding conductors, and these induced currents will form eddy currents, further increasing the loss. The ring magnet effectively reduces the leakage of magnetic flux through its closed ring structure, thereby reducing eddy current losses.
In a magnetic field, the edge of the magnet tends to produce a strong edge effect, which will lead to an uneven distribution of the magnetic field and increase eddy current losses. The design of the ring magnet reduces the impact of the edge effect by reducing the edge part, making the magnetic field distribution more uniform and reducing eddy current losses.
N35 NdFeB material has a high resistivity, which means that when the magnetic field changes, it generates a relatively small induced current. Induced current is the direct cause of eddy current loss, so high resistivity materials can significantly reduce eddy current losses.
N35 NdFeB material also has good hysteresis characteristics, that is, the magnetization process is relatively reversible and the hysteresis loss is low. Hysteresis loss is the energy consumed by the magnetic material during the magnetization and demagnetization process due to the reversal of magnetic domains, which is dissipated in the form of heat. Low hysteresis loss means that the material can use magnetic energy more efficiently and reduce energy loss during the change of the magnetic field.
N35 NdFeB material has extremely high magnetic energy product and coercive force, which enables it to provide a stronger magnetic driving force in the speaker. Stronger magnetic driving force means that the speaker can convert electrical energy into sound energy more efficiently, reducing energy loss during the conversion process, including eddy current loss.
The N35 NdFeB Ring Magnet For Loudspeaker achieves the effect of reducing eddy current loss through its ring design and high-quality material properties. This optimization not only improves the sound quality and efficiency of the speaker, but also makes the sound clearer and has a wider dynamic range, bringing a better listening experience to the audience.
