Frequently asked questions

What is the hole in a ring magnet for?
For mounting on a screw or a shaft. The bore may be cylindrical or countersunk for a screw head. The hole removes magnet volume, so a ring holds less than a disc of the same outside diameter.
What is the polarisation?
Axial as standard — poles on the flat faces of the ring. Diametrical polarisation is made to order.
What sizes are available?
Outside diameter from 5 to 62 mm from stock. To order up to 200 mm outside diameter, 180 mm bore and 40 mm height, with a lead time of 25–35 days.

Magnetic force weakens drastically with every mm of spacing. Remember that even a microscopic distance (e.g., contamination, varnish, veneer) noticeably weakens the grip. Magnets hold strongest during direct contact; air break weakens the power. Analyze how quickly the pull force drop, when the magnet does not adhere tightly to the metal substrate. When designing the assembly, eliminate unnecessary gaps.

When mounting a element on a upright wall (e.g., a fridge), it will maintain just approx. 20%-30% of its maximum pull force. Gravity and a weak degree of grip mean that products slide down easier than they detach. Planning a wall mount? Remember that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the element will give way down under a noticeably lighter weight. Application of an anti-slip layer can drastically improve the result.

A thin sheet is unable to take in the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a weak sheet, the field will pass right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation means that on thin elements (e.g., car bodies), the product holds weaker. We advise picking the steel cross-section based on the following data.

Classic neodymiums irreversibly lose power after exceeding the maximum temperature. Protect against heat – excessive heat can permanently damage this magnet. With increasing heat, the neodymium's power momentarily drops. Avoid using this magnet close to ovens exceeding its safe range. Too high temperature will result in irreversible degradation of magnetic properties.
*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a further horizon of performance. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Remember that when connecting a pair of magnets, the collision energy is huge. The levitation is slightly lower than the connection force, but still impressive.
*Flux density between like poles reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Note: Figures apply to shear force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronic devices as well as pacemakers. These neodymiums produce a flux that disrupts operation of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are delicate – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can cause material chips or injury to fingers. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Use safety goggles when handling with large magnets.

1. Shear force

*Warning: On a vertical surface, the magnet holds just ~20% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.34

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The Pc (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher Pc value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

The ring magnet with a hole MP 12x5x2 / N38 is created for permanent mounting, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables quick installation to wood, wall, plastic, or metal. This product with a force of 1.15 kg works great as a door latch, speaker holder, or spacer element in devices.
This is a crucial issue when working with model MP 12x5x2 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. One turn too many can destroy the magnet, so do it slowly. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.
These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. Damage to the protective layer during assembly is the most common cause of rusting. If you must use it outside, paint it with anti-corrosion paint after mounting.
The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Aesthetic mounting requires selecting the appropriate head size.
It is a magnetic ring with a diameter of 12 mm and thickness 2 mm. The key parameter here is the lifting capacity amounting to approximately 1.15 kg (force ~11.29 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 5 mm.
These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Pros as well as cons of Nd2Fe14B magnets.

Pros

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • They do not lose power, even over nearly ten years – the reduction in strength is only ~1% (according to tests),
  • They do not lose their magnetic properties even under close interference source,
  • Thanks to the metallic finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
  • They show high magnetic induction at the operating surface, which improves attraction properties,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
  • Considering the option of accurate forming and customization to individualized solutions, NdFeB magnets can be produced in a variety of geometric configurations, which amplifies use scope,
  • Universal use in future technologies – they serve a role in magnetic memories, electric motors, medical devices, also technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of neodymium magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
  • We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex forms.
  • Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
  • Due to neodymium price, their price is relatively high,

Holding force characteristics

Maximum lifting capacity of the magnet – what contributes to it?

The specified lifting capacity represents the peak performance, measured under laboratory conditions, meaning:
  • with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
  • with a cross-section no less than 10 mm
  • characterized by smoothness
  • with total lack of distance (without paint)
  • under axial force vector (90-degree angle)
  • at conditions approx. 20°C

Determinants of lifting force in real conditions

Bear in mind that the magnet holding will differ influenced by elements below, in order of importance:
  • Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Direction of force – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
  • Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted to the other side.
  • Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and holding force.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
  • Thermal environment – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safety rules for work with NdFeB magnets
Permanent damage

Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.

Beware of splinters

Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Do not give to children

Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are fatal.

Threat to navigation

Remember: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.

Do not drill into magnets
