Magnetic force weakens drastically with every subsequent millimeter of gap. Note that even the smallest gap (e.g., dirt, varnish, veneer) strongly weakens the grip. Neodymiums work strongest during direct contact; distance kills the force. Notice how flashily the load capacity drop, when the product does not touch tightly to the steel surface. When calculating the assembly, avoid unnecessary gaps.

The following data calculates the estimated holding capacity sufficient to initiate the slippage of the magnet downwards against a upright metal surface (assuming typical friction). This value is relative to the air gap between the magnet and the metal.

When hanging a magnet on a vertical surface (e.g., a car body), it will only hold barely approx. 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that magnets slip faster than they detach. Planning a vertical fastening? Consider that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the element will slide down under a significantly smaller cargo. Utilizing a rubberized pad can drastically raise the stability.

A thin metal plate is unable to focus the full magnetic flux, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you require a sufficiently solid backing of metal. The material oversaturation causes that on thin elements (e.g., thin profiles), the product works worse. We suggest choosing the steel cross-section according to the table below.

Classic neodymiums irreversibly lose power past the thermal threshold. Protect against heat – heat can permanently destroy this magnet. As the temperature rises, the neodymium's capacity temporarily lowers. Refrain from using this magnet close to heaters exceeding its operating temperature limit. Exceeding the critical threshold will result in permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a wider radius of action. Designing a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
Important: Results apply to sliding force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronic devices and pacemakers. These neodymiums generate a flux that prevents correct functioning of digital equipment. Notice: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MP 20x5x27 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	14.49 km/h (4.02 m/s)	0.48 J
30 mm	23.09 km/h (6.42 m/s)	1.23 J
50 mm	29.73 km/h (8.26 m/s)	2.03 J
100 mm	42.03 km/h (11.68 m/s)	4.07 J

Magnetic elements are prone to chipping – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Use safety goggles when handling with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical surface, the magnet holds just ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.16

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.

The ring-shaped magnet MP 20x5x27 / 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 20x5x27 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force 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.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. 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. 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.

This model is characterized by dimensions Ø20x27 mm and a weight of 59.64 g. The key parameter here is the holding force amounting to approximately 10.36 kg (force ~101.60 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.

Strengths and weaknesses of rare earth magnets.

Pros

Besides their immense strength, neodymium magnets offer the following advantages:

They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
They retain their magnetic properties even under external field action,
A magnet with a smooth nickel surface is more attractive,
Magnets are characterized by exceptionally strong magnetic induction on the active area,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
Thanks to the possibility of precise shaping and adaptation to unique needs, neodymium magnets can be created in a broad palette of shapes and sizes, which amplifies use scope,
Significant place in modern industrial fields – they are commonly used in data components, electric motors, medical devices, also modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets decrease their force 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 durability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We suggest casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
Due to neodymium price, their price is relatively high,

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

The lifting capacity listed is a theoretical maximum value executed under standard conditions:

with the contact of a sheet made of special test steel, ensuring maximum field concentration
whose transverse dimension reaches at least 10 mm
characterized by lack of roughness
with total lack of distance (without impurities)
during detachment in a direction vertical to the mounting surface
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

During everyday use, the actual holding force depends on several key aspects, ranked from the most important:

Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

Implant safety

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

Machining danger

Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.

Magnetic media

Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.

Handling guide

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Danger to the youngest

Only for adults. Small elements can be swallowed, causing severe trauma. Store out of reach of kids and pets.

Allergy Warning

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.

Physical harm

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

Heat sensitivity

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

GPS and phone interference

Remember: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, device, and GPS.

Shattering risk

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