Pulling power drops significantly per each millimeter of spacing. Note that even a microscopic distance (e.g., dirt, varnish, rust) strongly reduces the pull force. Neodymiums work most effectively at the point of direct contact; gap kills the force. Analyze how flashily the parameters fall, when the magnet does not touch tightly to the metal substrate. When planning the arrangement, eliminate additional spacers.

This section calculates the approximate weight limit needed to initiate the downward movement of the magnet vertically against a vertical metal surface (assuming typical friction coefficient). This value varies with the air gap between the magnet and the metal.

When mounting a magnet on a vertical wall (e.g., a board), it will maintain barely about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that magnets slip easier than they pull off. Designing a vertical fastening? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a much lighter weight. Utilizing a rubberized pad can drastically improve the result.

A thin sheet is incapable of focus the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a too thin substrate, the field will pass right through and the pull force will drop sharply. To achieve 100% of this neodymium's power, you need a suitably thick piece of steel. The saturation effect causes that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel dimension from these parameters.

Classic neodymiums irreversibly lose power after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's capacity temporarily lowers. Refrain from using this magnet close to heaters higher than its operating temperature limit. Ignoring the limit will cause destruction of magnetism.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel setup. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Want to build a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is huge. The repulsion force is marginally weaker than the attraction, but still large.
*Field value between like poles is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Calculations apply to sliding force of dual same magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to electronic devices and medical implants. These magnets generate a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can cause material chips or injury to skin. Be sure to control the product during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when playing with powerful specimens.

Environment	Effective steel pull	Effect

Water (riverbed)	2.16 kg (+0.27 kg buoyancy gain)	+14.5%

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

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. Vertical hold

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

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Heat tolerance

*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

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.

Component MPL 25x15x2 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 18.53 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

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 1.89 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 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 hidden locks in furniture making and mounting elements in automation. 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 (25x15 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: 25 mm (length), 15 mm (width), and 2 mm (thickness). 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.

Pros and cons of neodymium magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They do not lose power, even during around ten years – the drop in lifting capacity is only ~1% (according to tests),
They do not lose their magnetic properties even under close interference source,
Thanks to the glossy finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
Magnetic induction on the working layer of the magnet turns out to be exceptional,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of precise modeling and adjusting to individual applications,
Wide application in advanced technology sectors – they are commonly used in hard drives, drive modules, medical devices, also complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in strength. 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
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited possibility of creating nuts in the magnet and complicated forms - preferred is cover - mounting mechanism.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

The specified lifting capacity represents the maximum value, recorded under ideal test conditions, specifically:

on a base made of mild steel, perfectly concentrating the magnetic field
with a cross-section of at least 10 mm
characterized by lack of roughness
with zero gap (no coatings)
under axial force vector (90-degree angle)
in neutral thermal conditions

Determinants of lifting force in real conditions

In practice, the actual lifting capacity depends on many variables, ranked from the most important:

Gap (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Angle of force application – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
Surface structure – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.

H&S for magnets

Demagnetization risk

Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.

Keep away from computers

Do not bring magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.

Magnet fragility

Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.

Flammability

Dust created during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Warning for heart patients

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Impact on smartphones

GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Handling rules

Handle with care. Neodymium magnets act from a long distance and connect with huge force, often faster than you can move away.

Allergy Warning

Certain individuals experience a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Extended handling might lead to dermatitis. It is best to use protective gloves.

No play value

Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep out of reach of kids and pets.

Pinching danger

Big blocks can break fingers instantly. Do not put your hand between two strong magnets.
