Neodymium Ring Magnets Strong Rare Earth speaker Magnets
Neodymium ring magnets are strong Rare-Earth magnets, circular in shape with a hollow center. Neodymium (also known as “Neo”, “NdFeb” or “NIB”) ring Neodymium Magnets.
$300.00 total minimum order (excluding shipping & tax if applicable) -Items can be combined to reach the minimum amount.
Approximate Pull Information
The approximate pull info listed is for reference only.
These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate.
Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force.
Please be sure to test the actual pull in your actual application.
For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.
Our neodymium discs are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles).
Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings.
Standard tolerances are +/- 0.005” on both diameter and thickness dimensions.

To get a good idea of the physics behind the functioning of a loudspeaker watch the video above.
In short, the loudspeaker uses the interaction between the temporary magnetism generated in a coil of current carrying wire and the permanent magnetism generated by a stationary neodymium magnet.

Neodymium Speaker Magnets
Speakers operate by using a magnetic field to generate motion in a coil and speaker cone to project an amplified sound signal.
In neodymium speakers, the rare-earth element is used as the primary material in the magnets that create the field needed to drive the speakermovement.
Neodymium magnets made high-fidelity ear buds possible, as they can pack a strong magnetic field into a tiny package.
