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 decreases significantly with every mm of gap. Note that even the smallest gap (e.g., contamination, varnish, dust) noticeably diminishes the holding power. Magnetic products hold most effectively during direct contact; gap drastically cuts the power. Notice how flashily the pull force plummet, when the product does not touch directly to the steel surface. When designing the arrangement, eliminate additional spacers.

When placing a magnet on a vertical surface (e.g., a fridge), it you can count on just about 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient cause that magnets move down faster than they pop off the substrate. Want to create a wall mount? Note that the sliding force is significantly lower than the maximum static pull force. On a smooth steel, the magnet will slip down under a noticeably lighter load. Using a rubber pad can effectively raise the stability.

A thin metal plate is not enough to conduct the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To squeeze 100% of this magnet's potential, you require a sufficiently solid element of metal. The saturation effect causes that on thin elements (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel thickness according to the table below.

Classic neodymiums irreversibly lose strength after exceeding the maximum temperature. Protect against heat – excessive heat can permanently demagnetize this product. With increasing heat, the neodymium's force temporarily decreases. Refrain from using this product in hot environments exceeding its working range. Ignoring the limit will cause irreversible degradation of magnetism.
*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet setup. Such a system of two magnets creates a more powerful interaction and a larger range of performance. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is extreme. The repulsion force is slightly lower than the connection force, but still significant.
*Flux density between like poles reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Figures show sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Magnetic elements are prone to chipping – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Kinetic force can cause material chips or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when working with powerful specimens.

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds only approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.03

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-shaped magnet MP 25x5x5 / 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. It is also often used in advertising for fixing signs and in workshops for organizing tools.
This is a crucial issue when working with model MP 25x5x5 / 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. It's a good idea to use a flexible washer under the screw head, which will cushion the stresses. 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. 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 inside building 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 5 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. Aesthetic mounting requires selecting the appropriate head size.
The presented product is a ring magnet with dimensions Ø25 mm (outer diameter) and height 5 mm. The key parameter here is the lifting capacity amounting to approximately 7.66 kg (force ~75.12 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. 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.

Advantages as well as disadvantages of neodymium magnets.

Strengths

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • Their power remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
  • They retain their magnetic properties even under strong external field,
  • The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnets possess extremely high magnetic induction on the outer side,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Thanks to the potential of precise molding and customization to custom projects, neodymium magnets can be modeled in a wide range of shapes and sizes, which amplifies use scope,
  • Wide application in modern industrial fields – they serve a role in mass storage devices, drive modules, precision medical tools, as well as technologically advanced constructions.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

Problematic aspects of neodymium magnets and ways of using them
  • At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
  • Potential hazard resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Highest magnetic holding force – what affects it?

Information about lifting capacity was defined for the most favorable conditions, taking into account:
  • using a plate made of high-permeability steel, acting as a magnetic yoke
  • whose thickness reaches at least 10 mm
  • with a plane free of scratches
  • without the slightest air gap between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • at conditions approx. 20°C

Determinants of lifting force in real conditions

It is worth knowing that the magnet holding will differ depending on the following factors, in order of importance:
  • Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
  • Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
  • Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.

H&S for magnets
Beware of splinters

Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.

Operating temperature

Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.

Bone fractures

Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Allergic reactions

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and wear gloves.

Cards and drives

Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).

Implant safety

Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Conscious usage

Use magnets with awareness. Their huge power can shock even experienced users. Stay alert and do not underestimate their power.

Phone sensors

Be aware: rare earth magnets generate a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and GPS.

Mechanical processing

Powder created during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Keep away from children

Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Store away from kids and pets.
