Pulling power drops drastically with every mm of spacing. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) significantly weakens the grip. Magnets operate most effectively at the point of direct contact; gap nullifies the force. Notice how quickly the parameters fall, when the product does not adhere directly to the metal substrate. When designing the arrangement, discard unnecessary gaps.

This section presents the theoretical holding capacity required to start the downward movement of the magnet downwards along a vertical metal surface (considering typical friction coefficient). The holding force varies with the air gap between the magnet and the surface.

When placing a holder on a upright surface (e.g., a board), it will only hold just approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient cause that magnets slip easier than they pop off the substrate. Planning a wall mount? Note that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a noticeably lighter cargo. Using a rubber coating can effectively raise the stability.

A thin sheet cannot take in the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation means that on thin elements (e.g., appliance housings), the holder works worse. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Protect against heat – heat can permanently damage this product. With every degree above norm, the neodymium's capacity momentarily lowers. Do not use this magnet close to heaters higher than its safe range. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet combination. The connection of two magnets creates a more powerful interaction and a wider radius of performance. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the impact force is extreme. The repulsion force is a bit weaker than the connection force, but still impressive.
*Flux density in repulsion mode drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Estimates apply to sliding force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a large risk to electronic devices as well as medical implants. These NdFeB products produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Striking energy can cause material chips or injury to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when handling with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

*Note: On a vertical surface, the magnet retains just approx. 20-30% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely limits the holding force.

3. Temperature resistance

*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) = 0.31

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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 40x15x6 mm and a weight of 27 g, guarantees the highest quality connection. As a block magnet with high power (approx. 14.21 kg), this product is available immediately from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures 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. Watch your fingers! Magnets with a force of 14.21 kg can pinch very hard and cause hematomas. 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. 14.21 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to clean and degrease 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. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 40x15x6 mm, which, at a weight of 27 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 14.21 kg (force ~139.45 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of rare earth magnets.

Advantages

Besides their tremendous strength, neodymium magnets offer the following advantages:

They do not lose power, even after around ten years – the decrease in lifting capacity is only ~1% (based on measurements),
They possess excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold, or silver gives an professional appearance,
They are known for high magnetic induction at the operating surface, which increases their power,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Possibility of detailed modeling and modifying to complex requirements,
Wide application in high-tech industry – they are utilized in mass storage devices, drive modules, diagnostic systems, and multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their strength 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 durability even at temperatures up to 230°C
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic holder.
Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these products can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Best holding force of the magnet in ideal parameters – what contributes to it?

The lifting capacity listed is a measurement result performed under standard conditions:

on a plate made of mild steel, effectively closing the magnetic flux
whose thickness is min. 10 mm
with a plane perfectly flat
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (in the magnet axis)
in stable room temperature

Determinants of lifting force in real conditions

Please note that the working load may be lower influenced by elements below, starting with the most relevant:

Distance – the presence of foreign body (paint, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.

H&S for magnets

Hand protection

Pinching hazard: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.

Skin irritation risks

Some people suffer from a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Frequent touching can result in skin redness. It is best to use protective gloves.

Threat to navigation

Navigation devices and smartphones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Health Danger

Warning for patients: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

No play value

Neodymium magnets are not intended for children. Swallowing a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.

Beware of splinters

Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Do not underestimate power

Be careful. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.

Threat to electronics

Data protection: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).

Maximum temperature

Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).

Fire warning

Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
