Magnetic force decreases sharply with every subsequent millimeter of gap. Remember that even a very thin break (e.g., contamination, varnish, veneer) significantly diminishes the holding power. Magnetic products work most effectively at the point of direct contact; gap weakens the force. Observe how quickly the load capacity drop, when the magnet does not touch directly to the steel surface. When planning the arrangement, discard unnecessary gaps.

The following data defines the approximate shear load needed to start the slippage of the magnet vertically along a vertical steel wall (considering typical friction coefficient). The holding force is relative to the separation distance between the magnet and the surface.

When mounting a element on a vertical plane (e.g., a fridge), it will maintain barely approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip cause that magnets move down faster than they pop off the substrate. Want to create a vertical fastening? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a significantly smaller weight. Using a rubber coating can significantly improve the result.

A thin sheet is not enough to take in the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's power, you require a sufficiently solid backing of steel. The saturation effect means that on thin elements (e.g., car bodies), the magnet holds weaker. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products lose strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly damage this product. With every degree above norm, the magnet's force briefly lowers. Refrain from using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will result in destruction of magnetism.

*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and steel setup. The connection of two magnets produces a massive flux and a wider radius of action. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is huge. The levitation is a bit weaker than the connection force, but still impressive.
*Field value for N-N configuration drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Results demonstrate shear force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a real danger to IT equipment as well as pacemakers. These neodymiums generate a flux that destroys function of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when working with powerful specimens.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.62

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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 P_c (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 P_c 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.

MPL 45x25x10 / N38 - lamellar magnet

35.01 ZŁ brutto / pcs

The ring-shaped magnet MP 60x20x5 / 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 9.41 kg works great as a door latch, speaker holder, or spacer element in devices.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. 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 does not ensure full waterproofing. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for indoor use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

The inner hole diameter determines the maximum size of the mounting element. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Aesthetic mounting requires selecting the appropriate head size.

The presented product is a ring magnet with dimensions Ø60 mm (outer diameter) and height 5 mm. The key parameter here is the holding force amounting to approximately 9.41 kg (force ~92.27 N). The mounting hole diameter is precisely 20 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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.

Pros as well as cons of neodymium magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They do not lose magnetism, even during around 10 years – the reduction in strength is only ~1% (according to tests),
They are noted for resistance to demagnetization induced by external disturbances,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
In view of the potential of flexible forming and adaptation to custom needs, magnetic components can be created in a broad palette of geometric configurations, which makes them more universal,
Key role in future technologies – they serve a role in mass storage devices, electromotive mechanisms, advanced medical instruments, as well as complex engineering applications.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their 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.
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of making threads in the magnet and complex shapes - recommended is casing - mounting mechanism.
Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these devices are able to complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum holding power of the magnet – what affects it?

The specified lifting capacity represents the maximum value, obtained under optimal environment, namely:

on a base made of mild steel, perfectly concentrating the magnetic field
possessing a massiveness of at least 10 mm to avoid saturation
with an polished touching surface
without the slightest air gap between the magnet and steel
for force acting at a right angle (pull-off, not shear)
in stable room temperature

Determinants of lifting force in real conditions

Holding efficiency is affected by working environment parameters, including (from most important):

Clearance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
Temperature – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under shearing force 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 decreases the holding force.

Safety rules for work with NdFeB magnets

Nickel allergy

Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or choose encased magnets.

Keep away from computers

Equipment safety: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).

Precision electronics

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

Product not for children

Strictly store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.

Do not drill into magnets

Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

ICD Warning

Patients with a heart stimulator should maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.

Operating temperature

Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Material brittleness

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets leads to them shattering into small pieces.

Hand protection

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.

Do not underestimate power

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
