Grip strength weakens sharply with every mm of distance. Remember that even a microscopic distance (e.g., dirt, varnish, dust) noticeably diminishes the holding power. Neodymiums hold optimally in perfect adhesion; air break nullifies the force. Observe how flashily the parameters drop, when the magnet does not touch tightly to the steel surface. When planning the assembly, discard additional spacers.

The table below presents the estimated holding capacity sufficient to initiate the shifting of the magnet vertically against a vertical steel wall (considering standard friction coefficient). The holding force is relative to the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 5x4x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.21 lbs 96.0 g / 0.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.06 kg / 0.14 lbs 64.0 g / 0.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 lbs 32.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.16 kg / 0.35 lbs 160.0 g / 1.6 N

When hanging a element on a vertical wall (e.g., a board), it will maintain just approx. 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient cause that products move down faster than they pull off. Want to create a hanger? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter weight. Utilizing a rubberized layer can significantly increase the grip.

12 mm	100%	0.32 kg / 0.71 lbs 320.0 g / 3.1 N

A thin sheet is unable to absorb the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a thin surface, the field will penetrate right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you need a suitably thick element of metal. The material oversaturation causes that on thin elements (e.g., appliance housings), the product holds weaker. We advise picking the steel dimension according to the table below.

Standard neodymium magnets change their properties strength past the thermal threshold. Protect against heat – high temperature can permanently destroy this magnet. As the temperature rises, the neodymium's power momentarily lowers. Avoid using this magnet close to heaters exceeding its operating temperature limit. Too high temperature will result in destruction of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization under lower heat stress than taller cylinders. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and steel combination. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of action. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the collision energy is massive. The repulsion force is slightly lower than the connection force, but still significant.
*Field value for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Estimates apply to sliding force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a large risk to electronic devices as well as medical implants. These neodymiums generate a flux that disrupts operation of digital equipment. Be aware: the unseen radiation passes through tissues and plastic. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can cause material chips or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear safety glasses when playing with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. 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 wall, the magnet holds merely ~20% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly reduces 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) = 0.29

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.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 5x4x1 mm and a weight of 0.15 g, guarantees the highest quality connection. As a magnetic bar with high power (approx. 0.32 kg), this product is available off-the-shelf 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 shifting 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. To separate the MPL 5x4x1 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. Thanks to the flat surface and high force (approx. 0.32 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 5x4x1 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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. In practice, this means that this magnet has the greatest attraction force on its main planes (5x4 mm), which is ideal for flat mounting. 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), 4 mm (width), and 1 mm (thickness). The key parameter here is the holding force amounting to approximately 0.32 kg (force ~3.16 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of rare earth magnets.

Benefits

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

They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the surface of the magnet turns out to be extremely intense,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
Thanks to the option of precise molding and customization to individualized requirements, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which makes them more universal,
Fundamental importance in innovative solutions – they are used in hard drives, electric motors, precision medical tools, also complex engineering applications.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets decrease their power 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 stability even at temperatures 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 casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Highest magnetic holding force – what affects it?

The declared magnet strength refers to the maximum value, measured under laboratory conditions, meaning:

with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
with a cross-section of at least 10 mm
with an ground touching surface
with total lack of distance (no impurities)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Determinants of practical lifting force of a magnet

It is worth knowing that the application force may be lower depending on the following factors, in order of importance:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Angle of force application – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Handling guide

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.

Magnet fragility

Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Adults only

Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.

Warning for allergy sufferers

A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Extended handling can result in an allergic reaction. We strongly advise use safety gloves.

Threat to navigation

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

Dust is flammable

Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

Medical implants

Individuals with a pacemaker should maintain an large gap from magnets. The magnetism can stop the functioning of the implant.

Data carriers

Device Safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Operating temperature

Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

Physical harm

Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
