Oval Neodymium Magnets

An oval neodymium magnet is a sintered NdFeB magnet shaped into an ellipse, with two flat faces and a smooth, continuous curved edge. It offers the magnetic strength of rare earth material in a footprint that fits where conventional round magnets may be too wide.

The elongated profile is particularly useful in furniture fittings, narrow recesses, and assemblies where the available mounting area is longer than it is wide. Instead of redesigning the surrounding hardware to accommodate a circular magnet, an oval magnet can follow the shape of the existing space.

That is the real advantage of the ellipse: it makes magnetic holding possible in places where a round disc would be awkward to install.

Oval neodymium magnets are specified by three dimensions: length × width × thickness (L × W × T).

The table below covers our standard size range. Pull force is measured under controlled conditions against a clean, thick mild steel plate, with the magnet pulled directly away from the surface.

Note: Published pull force values represent laboratory test conditions. Actual holding performance depends on the thickness and composition of the steel target, surface finish, air gap, and direction of loading. A magnet that performs well in direct pull may provide considerably less resistance to sideways sliding.

For applications involving painted panels, thin steel, or concealed mounting, we recommend evaluating the holding force under actual installation conditions.

Cabinet doors are one of the most natural applications for oval magnets. An oval magnet recessed into a narrow door edge can work with a steel strike plate to create a concealed magnetic catch. The door stays closed without a visible latch, while the hardware remains hidden when the cabinet is shut.

Drawer fronts use the same principle. A magnet positioned behind the front panel provides a simple closing mechanism without occupying the space required by conventional mechanical catches.

Display manufacturers use oval magnets along slim panel edges, where a circular magnet of comparable face area might extend beyond the available mounting surface. The elongated shape allows the magnetic contact to follow the panel geometry while keeping the fixing out of sight.

In workholding fixtures, an oval magnet can also serve as a magnetic retaining element inside an elongated pocket. The pocket geometry determines how the component is located, while the magnet supplies the holding force.

These applications have different requirements, but they share one constraint: the magnet must fit the assembly rather than force the assembly to fit the magnet.

Oval neodymium magnets are manufactured from sintered NdFeB blanks and precision-ground to the required length, width, and thickness.

The continuous elliptical edge requires careful finishing. Sharp edges are lightly relieved before coating to reduce the risk of chipping during handling and installation. Typical dimensional tolerances are approximately ±0.1 mm, subject to magnet size and drawing requirements.

Nickel-copper-nickel (Ni-Cu-Ni) plating is the standard surface finish, providing a smooth metallic appearance and corrosion protection under normal indoor conditions.

For applications exposed to occasional moisture or frequent handling, epoxy coating may be specified. However, neither coating makes the magnet suitable for prolonged water immersion.

Standard magnetization is axial, with the north and south poles located on the two broad elliptical faces. This arrangement is suitable for face-to-face holding against steel plates or mating magnetic components.

Alternative magnetization requirements should be reviewed against the intended assembly and manufacturing process before production.

An oval magnet is often selected because a standard circular magnet will not fit the available space. For that reason, the dimensions of the recess are just as important as the magnetic holding requirement.

When requesting a quotation, provide the required length, width, thickness, quantity, and intended application. If the magnet will be installed behind a covering material or used against a particular steel component, include those details as well.

We can review non-standard oval dimensions against your drawings and confirm the appropriate NdFeB grade, coating, magnetization direction, and manufacturing tolerances before quoting.

The aim is straightforward: a magnet that fits the available space and delivers the holding performance your assembly actually needs.
