Grip strength drops significantly per each millimeter of gap. Remember that even a very thin break (e.g., dirt, varnish, dust) strongly reduces the pull force. Neodymiums work most effectively at the point of direct contact; distance drastically cuts the power. See how quickly the parameters drop, when the magnet does not adhere tightly to the metal substrate. When planning the mounting, eliminate redundant distances.

This section shows the theoretical holding capacity necessary to initiate the slippage of the magnet vertically on a upright steel plate (assuming typical friction). This parameter is a function of the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.11 kg / 4.65 pounds 2109.0 g / 20.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.41 kg / 3.10 pounds 1406.0 g / 13.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.70 kg / 1.55 pounds 703.0 g / 6.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.52 kg / 7.75 pounds 3515.0 g / 34.5 N

When mounting a element on a vertical surface (e.g., a board), it will maintain barely about 1/5 of its nominal power. Gravity and a weak degree of grip mean that magnets slide down easier than they detach. Designing a hanger? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a noticeably lighter cargo. Using a rubber coating can effectively increase the grip.

12 mm	100%	7.03 kg / 15.50 pounds 7030.0 g / 69.0 N

A too thin steel cannot focus the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To utilize the maximum of this magnet's potential, you need a suitably thick backing of steel. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Classic neodymiums lose power above the temperature limit. Watch out for overheating – heat can irreversibly destroy this magnet. With every degree above norm, the neodymium's power momentarily lowers. Avoid using this product close to ovens higher than its safe range. Ignoring the limit will lead to permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and steel setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the collision energy is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*Field value between like poles reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
* Estimates demonstrate sliding force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to electronic devices and medical implants. These NdFeB products produce a field that prevents correct functioning of digital equipment. Remember: the unseen radiation passes through tissues and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can cause material chips or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the magnet. Use safety goggles when handling with powerful specimens.

Warning: 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) severely limits the holding force.

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.46

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.

Component MPL 30x5x5 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 7.03 kg), this product is available immediately from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 7.03 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 30x5x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 30x5x5 / N38, it is best to use strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 30x5x5 / N38 model is magnetized axially (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (30x5 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 30 mm (length), 5 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 7.03 kg (force ~68.96 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Apart from their superior magnetism, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
They possess excellent resistance to magnetic field loss due to external fields,
In other words, due to the reflective surface of silver, the element becomes visually attractive,
Magnets are characterized by impressive magnetic induction on the outer side,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of precise shaping and modifying to atypical applications,
Huge importance in high-tech industry – they find application in data components, brushless drives, advanced medical instruments, as well as multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 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 prevent oxidation and corrosion.
We suggest a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can complicate diagnosis medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Maximum magnetic pulling force – what affects it?

Holding force of 7.03 kg is a result of laboratory testing performed under standard conditions:

using a base made of low-carbon steel, functioning as a ideal flux conductor
whose thickness reaches at least 10 mm
characterized by even structure
without any clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at temperature room level

Determinants of lifting force in real conditions

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

Distance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Warnings

Electronic hazard

Do not bring magnets close to a wallet, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

Choking Hazard

Adult use only. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.

Demagnetization risk

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Precision electronics

A strong magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.

Fragile material

Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets will cause them cracking into shards.

Dust is flammable

Dust produced during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Skin irritation risks

Medical facts indicate that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact and choose versions in plastic housing.

Respect the power

Exercise caution. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can react.

Crushing risk

Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Health Danger

For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
