Grip strength weakens drastically with every mm of distance. Keep in mind that even the smallest gap (e.g., dirt, paint, rust) significantly diminishes the holding power. Magnetic products work strongest during direct contact; air break nullifies the power. Analyze how rapidly the pull force drop, when the magnet does not touch tightly to the metal substrate. When designing the mounting, eliminate additional spacers.

The table below shows the estimated force sufficient to initiate the sliding of the magnet downwards on a upright steel wall (assuming standard friction). The holding force is a function of the gap size between the magnet and the metal.

When placing a magnet on a vertical wall (e.g., a board), it will maintain barely approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient mean that magnets slip faster than they pull off. Want to create a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slide down under a much lighter cargo. Utilizing a rubberized pad can effectively raise the stability.

A thin metal plate is not enough to focus the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a too thin substrate, the flux will pass right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you require a sufficiently solid backing of steel. The material oversaturation means that on thin elements (e.g., thin profiles), the product holds weaker. We advise picking the steel thickness according to the table below.

Ordinary NdFeB products change their properties power past the thermal threshold. Protect against heat – heat can permanently damage this product. With every degree above norm, the magnet's power momentarily lowers. Avoid using this magnet close to ovens higher than its working range. Ignoring the limit will cause destruction of magnetism.
*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) are more susceptible to demagnetization sooner than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a neodymium and metal combination. Such a system of magnet-to-magnet produces a massive flux and a larger range of performance. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is massive. The levitation is a bit weaker than the attraction, but still impressive.
*The magnetic induction between like poles is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Important: Results apply to sliding force of two same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a serious hazard to electronics and pacemakers. These magnets generate a flux that destroys function of digital equipment. Notice: the unseen radiation penetrates the body and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can trigger coating fragments or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when handling with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains only approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) drastically limits the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.13

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 20x5x5 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 6.49 kg works great as a cabinet closure, speaker holder, or mounting element in devices.
This is a crucial issue when working with model MP 20x5x5 / 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.
Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.
A screw or bolt with a thread diameter smaller than 5 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Always check that the screw head is not larger than the outer diameter of the magnet (20 mm), so it doesn't protrude beyond the outline.
The presented product is a ring magnet with dimensions Ø20 mm (outer diameter) and height 5 mm. The pulling force of this model is an impressive 6.49 kg, which translates to 63.68 N in newtons. The mounting hole diameter is precisely 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. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Strengths as well as weaknesses of neodymium magnets.

Strengths

Besides their durability, neodymium magnets are valued for these benefits:
  • They do not lose magnetism, even during approximately 10 years – the drop in power is only ~1% (theoretically),
  • Neodymium magnets are characterized by remarkably resistant to demagnetization caused by magnetic disturbances,
  • A magnet with a smooth gold surface has better aesthetics,
  • Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
  • Thanks to versatility in constructing and the capacity to customize to unusual requirements,
  • Significant place in high-tech industry – they are utilized in HDD drives, drive modules, diagnostic systems, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Weaknesses

Cons of neodymium magnets: tips and applications.
  • Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
  • Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
  • Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what contributes to it?

The declared magnet strength represents the limit force, obtained under optimal environment, specifically:
  • using a sheet made of mild steel, acting as a magnetic yoke
  • whose thickness equals approx. 10 mm
  • with an polished contact surface
  • without any insulating layer between the magnet and steel
  • under vertical force vector (90-degree angle)
  • in neutral thermal conditions

Lifting capacity in real conditions – factors

Effective lifting capacity is influenced by working environment parameters, such as (from most important):
  • Clearance – the presence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
  • Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
  • Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.

Precautions when working with NdFeB magnets
Do not underestimate power

Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

Magnetic interference

Note: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.

Do not overheat magnets

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.

Pacemakers

For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Risk of cracking

Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them cracking into small pieces.

Choking Hazard

These products are not toys. Eating several magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.

Safe distance

Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).

Skin irritation risks

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and opt for encased magnets.

Bodily injuries

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!

Dust explosion hazard

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