Grip strength decreases sharply with every mm of gap. Note that even the smallest gap (e.g., dirt, paint, veneer) significantly weakens the grip. Neodymiums hold strongest at the point of direct contact; distance nullifies the power. Observe how flashily the load capacity fall, when the magnet does not touch directly to the steel surface. When planning the arrangement, discard additional spacers.

The following data shows the estimated holding capacity required to initiate the sliding of the magnet downwards against a vertical steel wall (considering typical friction coefficient). The holding force is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 50x30x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.27 kg / 5.01 pounds 2271.0 g / 22.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.51 kg / 3.34 pounds 1514.0 g / 14.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.76 kg / 1.67 pounds 757.0 g / 7.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.79 kg / 8.34 pounds 3785.0 g / 37.1 N

When mounting a holder on a upright surface (e.g., a car body), it will maintain just about 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip cause that products slide down easier than they pull off. Planning a hanger? Remember that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the element will slide down under a significantly smaller cargo. Application of an anti-slip coating can drastically raise the stability.

12 mm	100%	7.57 kg / 16.69 pounds 7570.0 g / 74.3 N

A too thin steel is incapable of conduct the full magnetic flux, which wastes potential of the magnet. Should you attach a powerful product to a weak sheet, the field will pass right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's power, you need a suitably thick backing of metal. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the product shows lower pull force. We recommend selecting the steel thickness based on the following data.

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly damage this product. With every degree above norm, the neodymium's capacity briefly decreases. Avoid using this product close to ovens higher than its operating temperature limit. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a further horizon of performance. Designing a powerful holder? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The levitation is a bit weaker than the attraction, but still impressive.
*Field value for N-N configuration reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Estimates demonstrate friction force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronic devices and pacemakers. These neodymiums produce a flux that prevents correct functioning of digital equipment. Be aware: the unseen radiation passes through tissues and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can cause material chips or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack 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!

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Note: On a vertical surface, the magnet holds just a fraction of its perpendicular strength.

2. Steel thickness impact

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

3. Power loss vs temp

*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) = 0.14

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.

MPL 40x15x5x2[7/3.5] / N38 - lamellar magnet

15.07 ZŁ brutto / pcs

Component MPL 50x30x4 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 7.57 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 block 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 7.57 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.

They constitute a key element in the production of generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (50x30 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 50x30x4 mm, which, at a weight of 45 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 7.57 kg (force ~74.26 N), which, with such a flat shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of rare earth magnets.

Strengths

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

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
They do not lose their magnetic properties even under close interference source,
Thanks to the shiny finish, the plating of nickel, gold, or silver-plated gives an clean appearance,
Magnetic induction on the working layer of the magnet is very high,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
In view of the ability of flexible shaping and adaptation to specialized needs, neodymium magnets can be manufactured in a wide range of geometric configurations, which increases their versatility,
Huge importance in high-tech industry – they are used in magnetic memories, motor assemblies, advanced medical instruments, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices

Disadvantages

Problematic aspects of neodymium magnets and ways of using them

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend 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 strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited possibility of producing nuts in the magnet and complex forms - preferred is casing - magnet mounting.
Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
Due to expensive raw materials, their price exceeds standard values,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

Magnet power was determined for ideal contact conditions, assuming:

using a base made of mild steel, functioning as a ideal flux conductor
with a cross-section minimum 10 mm
with a surface cleaned and smooth
under conditions of no distance (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Lifting capacity in practice – influencing factors

Effective lifting capacity impacted by specific conditions, mainly (from most important):

Distance (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Plate material – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Thermal environment – heating the magnet results in weakening 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, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.

Safe handling of NdFeB magnets

Bodily injuries

Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Electronic devices

Equipment safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).

This is not a toy

Absolutely keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are very dangerous.

Phone sensors

An intense magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.

Conscious usage

Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can react.

Nickel coating and allergies

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.

Machining danger

Dust produced during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Risk of cracking

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Warning for heart patients

Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Do not overheat magnets

Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
