Pulling power decreases significantly per each millimeter of distance. Note that even the smallest gap (e.g., dirt, varnish, dust) strongly diminishes the holding power. Magnets work strongest during direct contact; distance drastically cuts the force. Observe how rapidly the pull force fall, when the product does not touch tightly to the metal substrate. When designing the mounting, avoid redundant distances.

The following data indicates the approximate force necessary to start the downward movement of the magnet downwards along a vertical steel plate (assuming standard friction). This parameter varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MPL 25x15x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.57 kg / 1.25 lbs 567.0 g / 5.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.83 lbs 378.0 g / 3.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 lbs 189.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.95 kg / 2.08 lbs 945.0 g / 9.3 N

When placing a element on a upright wall (e.g., a board), it will maintain only about 1/5 of its nominal power. Gravity as well as a weak degree of grip influence the fact that holders slide down faster than they pull off. Designing a vertical fastening? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a noticeably lighter cargo. Application of an anti-slip pad can effectively raise the stability.

12 mm	100%	1.89 kg / 4.17 lbs 1890.0 g / 18.5 N

A too thin steel is not enough to absorb the entire magnetic field, which wastes potential of the magnet. Should you mount a strong magnet to a thin surface, the field will penetrate right through and the pull force will drop sharply. To utilize 100% of this neodymium's potential, you need a suitably thick piece of metal. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel cross-section from these parameters.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly demagnetize this product. With increasing heat, the neodymium's force briefly drops. Refrain from using this product close to ovens exceeding its operating temperature limit. Too high temperature will lead to permanent loss of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties sooner than long magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. Such a system of two magnets produces a massive flux and a larger range of action. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is massive. The levitation is slightly lower than the attraction, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
Important: Figures refer to sliding force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a serious hazard to electronics and medical implants. These magnets generate a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can cause material chips or injury to skin. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the neodymium. Wear safety glasses when playing 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.

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

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

3. Power loss vs temp

*For N38 grade, the critical limit 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 13x10x5 / N35H - lamellar magnet

2.58 ZŁ brutto / pcs

Component MPL 25x15x2 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 1.89 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects 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. To separate the MPL 25x15x2 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 25x15x2 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 1.89 kg), they are ideal as closers in furniture making and mounting elements in automation. 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 25x15x2 / N38, it is best to use strong epoxy glues (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).

Standardly, the MPL 25x15x2 / N38 model is magnetized axially (dimension 2 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 25x15x2 mm, which, at a weight of 5.63 g, makes it an element with high energy density. It is a magnetic block with dimensions 25x15x2 mm and a self-weight of 5.63 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of neodymium magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They possess excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets are characterized by very high magnetic induction on the surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to freedom in shaping and the ability to customize to unusual requirements,
Huge importance in innovative solutions – they are utilized in mass storage devices, drive modules, medical equipment, also technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Problematic aspects of neodymium magnets and proposals for their use:

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing nuts and complex shapes in magnets, we recommend using cover - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
Due to complex production process, their price is higher than average,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

The declared magnet strength represents the peak performance, obtained under laboratory conditions, namely:

on a plate made of structural steel, effectively closing the magnetic flux
whose transverse dimension is min. 10 mm
with an ideally smooth touching surface
under conditions of gap-free contact (surface-to-surface)
during detachment in a direction vertical to the mounting surface
in temp. approx. 20°C

Lifting capacity in real conditions – factors

Real force is influenced by working environment parameters, such as (from most important):

Clearance – existence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be wasted to the other side.
Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.

H&S for magnets

Risk of cracking

Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets will cause them shattering into shards.

Medical interference

Individuals with a heart stimulator have to maintain an large gap from magnets. The magnetic field can stop the functioning of the implant.

Bodily injuries

Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.

Electronic devices

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

Do not give to children

Always store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.

Threat to navigation

Navigation devices and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Handling guide

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Operating temperature

Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.

Dust explosion hazard

Powder produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
