Magnetic force drops sharply per each millimeter of spacing. Remember that every additional insulation layer (e.g., dirt, varnish, rust) significantly weakens the grip. Magnets operate optimally in perfect adhesion; distance nullifies the power. Observe how flashily the pull force plummet, when the product does not adhere directly to the steel surface. When designing the assembly, avoid additional spacers.

The following data defines the estimated weight limit necessary to initiate the slippage of the magnet down on a upright steel wall (assuming typical friction coefficient). The holding force depends on the gap size between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 5x5x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.22 LBS 102.0 g / 1.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.07 kg / 0.15 LBS 68.0 g / 0.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 LBS 34.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.17 kg / 0.37 LBS 170.0 g / 1.7 N

When placing a element on a vertical plane (e.g., a car body), it will only hold barely approx. 1/5 of its nominal power. Gravity and a low friction coefficient mean that magnets slip faster than they pop off the substrate. Designing a vertical fastening? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter load. Utilizing a rubberized coating can effectively improve the result.

A thin metal plate is incapable of focus the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you need a suitably thick piece of metal. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the product holds weaker. We suggest choosing the steel cross-section according to the table below.

Classic neodymiums change their properties strength past the thermal threshold. Avoid high temperatures – heat can permanently damage this product. With every degree above norm, the neodymium's force temporarily drops. Do not use this magnet near heat sources exceeding its safe range. Exceeding the critical threshold will cause destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet produces a massive flux and a further horizon of performance. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the impact force is huge. The levitation is marginally weaker than the connection force, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Note: Results apply to friction force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a real danger to electronic devices and medical implants. These magnets generate a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and plastic. Special caution must be exercised 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, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MPL 5x5x1 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	42.67 km/h (11.85 m/s)	0.01 J

100 mm	134.91 km/h (37.48 m/s)	0.13 J

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or painful pinches to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when working with powerful specimens.

Corrosion 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Caution: On a vertical surface, the magnet retains just ~20% of its nominal pull.

2. Steel thickness impact

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

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.

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 5x5x1 mm and a weight of 0.19 g, guarantees the highest quality connection. As a block magnet with high power (approx. 0.34 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 0.34 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 fasteners 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 5x5x1 / N38, it is best to use two-component adhesives (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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 5 mm (length), 5 mm (width), and 1 mm (thickness). It is a magnetic block with dimensions 5x5x1 mm and a self-weight of 0.19 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros as well as cons of rare earth magnets.

Benefits

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

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
They have excellent resistance to weakening of magnetic properties as a result of external fields,
Thanks to the elegant finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
Magnetic induction on the surface of the magnet is maximum,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to versatility in shaping and the ability to adapt to specific needs,
Wide application in advanced technology sectors – they are utilized in computer drives, electric motors, precision medical tools, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions

Disadvantages

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We recommend a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex shapes.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

Holding force of 0.34 kg is a result of laboratory testing performed under the following configuration:

on a block made of structural steel, optimally conducting the magnetic flux
whose thickness reaches at least 10 mm
with a plane free of scratches
under conditions of no distance (metal-to-metal)
under vertical force direction (90-degree angle)
at ambient temperature room level

Practical aspects of lifting capacity – factors

Effective lifting capacity is influenced by working environment parameters, mainly (from priority):

Air gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Steel thickness – too thin sheet does not accept the full field, causing part of the flux to be lost to the other side.
Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Safe handling of NdFeB magnets

Adults only

Absolutely keep magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.

Fire risk

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Permanent damage

Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.

Skin irritation risks

Certain individuals experience a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Frequent touching might lead to skin redness. We recommend wear safety gloves.

Precision electronics

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.

Serious injuries

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Electronic devices

Avoid bringing magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Conscious usage

Use magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their power.

Material brittleness

Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them cracking into shards.

Medical implants

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
