Frequently asked questions

How much will a block magnet really hold?

The catalogue force is measured in full contact with smooth steel at least 10 mm thick, pulled perpendicular, at about 20 °C. On 1 mm sheet about 50% of that value remains, on 0.5 mm about 25%. Mounted on a vertical wall the realistic figure is 20–30%, because the load is then in shear rather than in tension.

What is the maximum working temperature?

Standard N-series grades up to 80 °C, and N50, N52 and N54 up to 60 °C. Above the maximum working temperature the loss stops being reversible. The Curie temperature, at which magnetic properties are lost completely, is about 310 °C.

What safety factor should I allow?

At least twice the mass of the item, and three to five times for vertical mounting. The margin covers sheet thickness, surface condition, any layer of paint or rust, and vibration.

Pulling power decreases significantly per each millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnets operate strongest in perfect adhesion; air break weakens the force. Observe how quickly the pull force drop, when the magnet does not adhere directly to the metal substrate. When planning the mounting, discard additional spacers.

The following data indicates the estimated holding capacity needed to initiate the slippage of the magnet vertically on a upright steel plate (assuming standard friction coefficient). This value depends on the gap size between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MPL 10x7x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.61 kg / 1.34 pounds 606.0 g / 5.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.40 kg / 0.89 pounds 404.0 g / 4.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.20 kg / 0.45 pounds 202.0 g / 2.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.01 kg / 2.23 pounds 1010.0 g / 9.9 N

When hanging a element on a upright wall (e.g., a fridge), it will only hold only approx. 1/5 of its nominal power. Gravity and a weak degree of grip mean that magnets slide down easier than they pop off the substrate. Planning a vertical fastening? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slip down under a significantly smaller cargo. Using a rubber layer can significantly raise the stability.

A thin metal plate is not enough to focus the full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's potential, you need a suitably thick backing of steel. The saturation effect means that on sheet metal structures (e.g., thin profiles), the magnet works worse. We suggest choosing the steel thickness based on the following data.

Classic neodymiums irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the neodymium's capacity momentarily drops. Do not use this magnet in hot environments higher than its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a much further distance than a magnet and sheet combination. The setup of two magnets creates a more powerful interaction and a larger range of operation. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still large.
*The magnetic induction between like poles drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Note: Results demonstrate friction force of dual same magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to electronics as well as medical implants. These NdFeB products generate a flux that destroys function of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when working with large magnets.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains merely a fraction of its nominal pull.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Thermal stability

*For standard magnets, 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) = 0.42

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 50x50x10 / N38 - lamellar magnet

42.88 zł brutto / pcs

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 10x7x3 mm and a weight of 1.58 g, guarantees the highest quality connection. As a block magnet with high power (approx. 2.02 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 2.02 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 10x7x3 / 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 hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 10x7x3 / N38, it is best to use 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 (10x7 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 10x7x3 mm, which, at a weight of 1.58 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 2.02 kg (force ~19.82 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Strengths

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

Their power is maintained, and after approximately ten years it drops only by ~1% (theoretically),
They are extremely resistant to demagnetization induced by presence of other magnetic fields,
Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Considering the ability of flexible molding and adaptation to individualized projects, magnetic components can be modeled in a variety of geometric configurations, which amplifies use scope,
Universal use in advanced technology sectors – they are utilized in mass storage devices, electric drive systems, precision medical tools, and technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce 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. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of creating nuts in the magnet and complicated forms - recommended is casing - magnetic holder.
Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

The lifting capacity listed is a measurement result performed under specific, ideal conditions:

on a plate made of structural steel, perfectly concentrating the magnetic flux
whose transverse dimension is min. 10 mm
with a plane free of scratches
without any air gap between the magnet and steel
for force acting at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Real force impacted by working environment parameters, mainly (from most important):

Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Steel thickness – too thin sheet causes magnetic saturation, causing part of the power to be escaped into the air.
Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets

Bone fractures

Big blocks can crush fingers instantly. Do not put your hand between two attracting surfaces.

Electronic devices

Data protection: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Magnets are brittle

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.

Maximum temperature

Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).

Conscious usage

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Product not for children

Product intended for adults. Small elements pose a choking risk, causing serious injuries. Store out of reach of kids and pets.

Sensitization to coating

It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact or opt for coated magnets.

Threat to navigation

GPS units and smartphones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Warning for heart patients

People with a heart stimulator should maintain an absolute distance from magnets. The magnetism can stop the operation of the life-saving device.

Dust explosion hazard

Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
