Magnetic force decreases significantly with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., contamination, paint, dust) significantly reduces the pull force. Magnets hold most effectively at the point of direct contact; distance weakens the power. Notice how rapidly the parameters fall, when the magnet does not touch directly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

The following data presents the approximate force needed to start the shifting of the magnet downwards along a vertical steel plate (assuming standard friction coefficient). The holding force varies with the air gap between the magnet and the surface.

When hanging a magnet on a vertical plane (e.g., a car body), it you can count on just approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that holders slide down faster than they pop off the substrate. Want to create a hanger? Consider that the shear force is much weaker than the maximum static pull force. On a painted metal, the element will give way down under a much lighter load. Application of an anti-slip pad can drastically raise the stability.

A thin sheet is incapable of focus the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a thin surface, the flux will pass right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you require a sufficiently solid piece of metal. The material oversaturation means that on thin elements (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel cross-section from these parameters.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently demagnetize this product. As the temperature rises, the neodymium's force briefly drops. Do not use this product close to ovens exceeding its operating temperature limit. Too high temperature will result in irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) may lose charge permanently at lower temperatures than long magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a much further distance than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the pinch force is huge. The levitation is a bit weaker than the attraction, but still large.
*Field value between like poles drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Attention: Figures demonstrate shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to electronic devices and medical implants. These magnets generate a field that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation acts through matter and housings. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can cause material chips or injury to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when working with powerful specimens.

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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical wall, the magnet retains just approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) drastically weakens the holding force.

3. Power loss vs temp

*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) = 0.51

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.

47.32 ZŁ brutto / pcs

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 30x10x8 mm and a weight of 18 g, guarantees the highest quality connection. As a block magnet with high power (approx. 12.13 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.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 30x10x8 / 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.

Plate magnets MPL 30x10x8 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 12.13 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 30x10x8 / N38, we recommend utilizing strong epoxy glues (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. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 30x10x8 mm, which, at a weight of 18 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 12.13 kg (force ~119.04 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of rare earth magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:

They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
They are resistant to demagnetization induced by external field influence,
In other words, due to the smooth finish of nickel, the element gains a professional look,
Magnetic induction on the working layer of the magnet remains extremely intense,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
Due to the possibility of flexible shaping and customization to individualized projects, neodymium magnets can be produced in a wide range of geometric configurations, which amplifies use scope,
Key role in modern technologies – they are utilized in data components, drive modules, diagnostic systems, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise 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
Limited ability of creating threads in the magnet and complex shapes - recommended is cover - magnet mounting.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these devices are able to complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Maximum holding power of the magnet – what it depends on?

Breakaway force was defined for ideal contact conditions, taking into account:

using a plate made of low-carbon steel, functioning as a ideal flux conductor
with a cross-section no less than 10 mm
characterized by even structure
with zero gap (without paint)
for force applied at a right angle (in the magnet axis)
at room temperature

Lifting capacity in practice – influencing factors

Please note that the magnet holding may be lower depending on the following factors, starting with the most relevant:

Distance (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or debris).
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets

Beware of splinters

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Electronic devices

Do not bring magnets close to a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease handling magnets and wear gloves.

Magnetic interference

Be aware: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Bone fractures

Risk of injury: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.

Conscious usage

Exercise caution. Neodymium magnets act from a distance and snap with massive power, often faster than you can move away.

Fire risk

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

Product not for children

Adult use only. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.

Thermal limits

Do not overheat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

ICD Warning

Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to handle the magnets.

Caution! More info about risks in the article: Magnet Safety Guide.
