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.

Pulling power drops sharply per each millimeter of gap. Note that even a very thin break (e.g., contamination, paint, veneer) significantly diminishes the holding power. Magnetic products hold most effectively at the point of direct contact; gap drastically cuts the power. Observe how flashily the parameters fall, when the product does not adhere flatly to the metal substrate. When calculating the arrangement, eliminate unnecessary gaps.

The table below calculates the estimated shear load needed to start the slippage of the magnet vertically along a upright steel plate (assuming standard friction). This value is a function of the distance between the magnet and the metal.

When mounting a element on a upright wall (e.g., a car body), it you can count on only approx. 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip mean that products slide down easier than they pop off the substrate. Want to create a wall mount? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a noticeably lighter weight. Using a rubber layer can effectively raise the stability.

A thin sheet is incapable of take in the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's potential, you require a sufficiently solid piece of metal. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We advise picking the steel cross-section from these parameters.

Classic neodymiums lose strength past the thermal threshold. Avoid high temperatures – heat can permanently demagnetize this product. With every degree above norm, the magnet's force temporarily drops. Refrain from using this product close to heaters higher than its working range. Ignoring the limit will cause destruction of magnetism.
*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) risk losing magnetic properties sooner than taller cylinders. The danger warning in the table signals permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Be careful that when bringing together two magnets, the pinch force is huge. The levitation is slightly lower than the connection force, but still large.
*Flux density between like poles is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Estimates apply to sliding force of dual identical magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to IT equipment as well as pacemakers. These NdFeB products produce a field that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Caution: On a vertical surface, the magnet holds merely a fraction of its perpendicular strength.

2. Steel saturation

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

3. Power loss vs temp

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.32

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. 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 2.21 kg works great as a door latch, speaker holder, or mounting element in devices.
This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure will cause the ring to crack. 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 does not ensure full waterproofing. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. This product is dedicated for indoor use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.
A screw or bolt with a thread diameter smaller than 8/4 mm fits this model. 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. Always check that the screw head is not larger than the outer diameter of the magnet (12 mm), so it doesn't protrude beyond the outline.
This model is characterized by dimensions Ø12x3 mm and a weight of 2.26 g. The key parameter here is the lifting capacity amounting to approximately 2.21 kg (force ~21.72 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 8/4 mm.
These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. In the case of connecting two rings, make sure one is turned the right way. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose power, even over around ten years – the drop in power is only ~1% (according to tests),
  • They do not lose their magnetic properties even under strong external field,
  • The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to look better,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
  • Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
  • In view of the ability of accurate forming and customization to custom projects, NdFeB magnets can be modeled in a variety of geometric configurations, which expands the range of possible applications,
  • Wide application in electronics industry – they are utilized in mass storage devices, drive modules, medical devices, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions

Disadvantages

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • Limited possibility of creating nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
  • Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these devices can disrupt the diagnostic process medical after entering the body.
  • With budget limitations the cost of neodymium magnets is a challenge,

Lifting parameters

Best holding force of the magnet in ideal parameters – what contributes to it?

The lifting capacity listed is a measurement result performed under standard conditions:
  • with the use of a sheet made of special test steel, ensuring maximum field concentration
  • whose transverse dimension is min. 10 mm
  • characterized by even structure
  • without any air gap between the magnet and steel
  • during detachment in a direction perpendicular to the mounting surface
  • in temp. approx. 20°C

Determinants of lifting force in real conditions

Bear in mind that the application force may be lower influenced by elements below, in order of importance:
  • Gap between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Material type – the best choice is high-permeability steel. Hardened steels may attract less.
  • Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

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

Precautions when working with neodymium magnets
Beware of splinters

Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Flammability

Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

ICD Warning

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.

Physical harm

Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Compass and GPS

A strong magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.

Conscious usage

Use magnets consciously. Their powerful strength can shock even professionals. Plan your moves and respect their force.

Swallowing risk

Always store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are fatal.

Maximum temperature

Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Safe distance

Avoid bringing magnets close to a purse, computer, or screen. The magnetism can destroy these devices and erase data from cards.
