Grip strength decreases significantly with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., dirt, varnish, dust) significantly reduces the pull force. Magnets hold most effectively in perfect adhesion; gap weakens the force. See how rapidly the pull force plummet, when the magnet does not adhere flatly to the metal substrate. When planning the arrangement, eliminate redundant distances.

This section indicates the estimated weight limit sufficient to cause the shifting of the magnet downwards along a vertical steel plate (assuming standard friction coefficient). The holding force varies with the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MP 10x7/3.5x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.56 kg / 564.0 g 5.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 376.0 g 3.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 188.0 g 1.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.94 kg / 940.0 g 9.2 N

When placing a magnet on a upright plane (e.g., a car body), it will maintain just about 1/5 of its nominal power. Gravity as well as a weak degree of grip mean that magnets move down faster than they pull off. Designing a vertical fastening? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will give way down under a significantly smaller weight. Using a rubber pad can effectively increase the grip.

Table 4: Steel thickness (substrate influence) - power losses
MP 10x7/3.5x3 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.19 kg / 188.0 g 1.8 N
1 mm	25%	0.47 kg / 470.0 g 4.6 N
2 mm	50%	0.94 kg / 940.0 g 9.2 N
5 mm	100%	1.88 kg / 1880.0 g 18.4 N
10 mm	100%	1.88 kg / 1880.0 g 18.4 N

A too thin steel cannot focus the full magnetic flux, which weakens actual performance of the magnet. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To squeeze full efficiency of this magnet's potential, you need a suitably thick piece of steel. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Table 5: Thermal resistance (material behavior) - power drop
MP 10x7/3.5x3 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	1.88 kg / 1880.0 g 18.4 N	OK
40 °C	-2.2%	1.84 kg / 1838.6 g 18.0 N	OK
60 °C	-4.4%	1.80 kg / 1797.3 g 17.6 N
80 °C	-6.6%	1.76 kg / 1755.9 g 17.2 N
100 °C	-28.8%	1.34 kg / 1338.6 g 13.1 N

Classic neodymiums irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently damage this product. As the temperature rises, the neodymium's power temporarily lowers. Do not use this product in hot environments higher than its working range. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) may lose charge permanently sooner than long magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and sheet combination. The setup of two magnets generates a stronger field and a wider radius of performance. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the collision energy is huge. The repulsion force is slightly lower than the connection force, but still large.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).

Table 7: Safety (HSE) (implants) - precautionary measures
MP 10x7/3.5x3 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	4.5 cm
Hearing aid	10 Gs (1.0 mT)	3.5 cm
Timepiece	20 Gs (2.0 mT)	3.0 cm

A strong magnetic field poses a large risk to electronic devices as well as pacemakers. These neodymiums produce a flux that prevents correct functioning of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	35.25 km/h (9.79 m/s)	0.07 J
30 mm	60.84 km/h (16.90 m/s)	0.22 J

100 mm	111.07 km/h (30.85 m/s)	0.74 J

Magnetic elements are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can cause material chips or injury to fingers. Always hold the magnet 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 means shattering of the magnet. Wear safety glasses when playing with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet retains just approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.37

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 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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Mounting is clean and reversible, unlike gluing. This product with a force of 1.88 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 great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force will cause the ring to crack. It's a good idea to use a rubber spacer under the screw head, which will cushion the stresses. 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.

It is a magnetic ring with a diameter of 10 mm and thickness 3 mm. The pulling force of this model is an impressive 1.88 kg, which translates to 18.47 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 7/3.5 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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 as well as weaknesses of Nd₂Fe₁₄B magnets.

Strengths

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

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
Neodymium magnets are highly resistant to demagnetization caused by magnetic disturbances,
Thanks to the shiny finish, the plating of nickel, gold-plated, or silver-plated gives an elegant appearance,
Magnetic induction on the working layer of the magnet turns out to be impressive,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
Possibility of custom creating and modifying to individual conditions,
Significant place in advanced technology sectors – they serve a role in hard drives, motor assemblies, advanced medical instruments, as well as complex engineering applications.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we recommend placing them in special holders. 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 advise our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Due to limitations in creating threads and complex forms in magnets, we recommend using casing - magnetic holder.
Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
Due to complex production process, their price is higher than average,

Holding force characteristics

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

Magnet power is the result of a measurement for the most favorable conditions, assuming:

on a block made of mild steel, perfectly concentrating the magnetic field
possessing a thickness of minimum 10 mm to avoid saturation
with a surface perfectly flat
with direct contact (without coatings)
for force acting at a right angle (pull-off, not shear)
at ambient temperature room level

What influences lifting capacity in practice

Bear in mind that the working load will differ subject to elements below, in order of importance:

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Plate thickness – insufficiently thick steel does not close the flux, causing part of the power to be lost into the air.
Material type – ideal substrate is pure iron steel. Stainless steels may attract less.
Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Warning for heart patients

Individuals with a ICD should keep an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Metal Allergy

It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and select versions in plastic housing.

Bone fractures

Large magnets can break fingers instantly. Do not put your hand between two strong magnets.

Dust explosion hazard

Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

Impact on smartphones

Remember: rare earth magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, device, and navigation systems.

Conscious usage

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

No play value

Always store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.

Thermal limits

Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Protective goggles

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Safe distance

Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
