Grip strength weakens significantly per each millimeter of spacing. Note that every additional insulation layer (e.g., dirt, varnish, veneer) strongly diminishes the holding power. Neodymiums hold optimally in perfect adhesion; air break drastically cuts the force. Analyze how flashily the parameters drop, when the magnet does not touch flatly to the metal substrate. When planning the mounting, avoid additional spacers.

The table below shows the estimated weight limit sufficient to initiate the slippage of the magnet downwards on a vertical metal surface (assuming typical friction coefficient). This parameter is relative to the distance between the magnet and the metal.

When hanging a element on a upright surface (e.g., a board), it will maintain only approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that holders slip easier than they pop off the substrate. Planning a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a much lighter cargo. Application of an anti-slip pad can drastically increase the grip.

A thin sheet cannot take in the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a thin surface, the field will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's potential, you require a sufficiently solid piece of metal. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the product works worse. We suggest choosing the steel thickness based on the following data.

Ordinary NdFeB products change their properties strength past the thermal threshold. Protect against heat – high temperature can permanently damage this magnet. As the temperature rises, the neodymium's force temporarily drops. Refrain from using this product in hot environments exceeding its working range. Ignoring the limit will cause destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently sooner compared to rod 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 neodymium and metal setup. The connection of two magnets produces a massive flux and a wider radius of performance. Want to build a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the collision energy is huge. The repulsion force is slightly lower than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Important: Calculations refer to shear force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a large risk to IT equipment and pacemakers. These magnets generate a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation passes through tissues and plastic. Special caution must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the magnet. Wear eye protection when handling 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.

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Shear force

*Note: On a vertical surface, the magnet retains only ~20% of its perpendicular strength.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) severely weakens the holding force.

3. Power loss vs temp

*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) = 0.46

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.

1488.30 ZŁ brutto / pcs

Component MPL 30x5x5 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 7.03 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.

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 7.03 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.

They constitute a key element in the production of wind generators and material handling systems. They work great as fasteners under tiles, wood, or glass. 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. 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. 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: 30 mm (length), 5 mm (width), and 5 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 7.03 kg (force ~68.96 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Pros

Besides their immense pulling force, neodymium magnets offer the following advantages:

They do not lose magnetism, even after around ten years – the reduction in power is only ~1% (theoretically),
Magnets perfectly protect themselves against loss of magnetization caused by external fields,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Possibility of exact machining as well as adjusting to atypical needs,
Significant place in future technologies – they are commonly used in hard drives, electric drive systems, precision medical tools, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Limited possibility of creating nuts in the magnet and complicated shapes - preferred is casing - magnet mounting.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Holding force characteristics

Highest magnetic holding force – what it depends on?

Holding force of 7.03 kg is a theoretical maximum value performed under the following configuration:

with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
possessing a massiveness of minimum 10 mm to ensure full flux closure
with a surface cleaned and smooth
without the slightest clearance between the magnet and steel
under axial application of breakaway force (90-degree angle)
in neutral thermal conditions

Practical aspects of lifting capacity – factors

Holding efficiency is affected by specific conditions, mainly (from priority):

Air gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Phone sensors

Be aware: neodymium magnets produce a field that disrupts precision electronics. Maintain a separation from your phone, tablet, and GPS.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness occurs, cease working with magnets and wear gloves.

Respect the power

Be careful. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.

Threat to electronics

Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).

Pinching danger

Big blocks can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.

Shattering risk

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.

No play value

Adult use only. Small elements can be swallowed, leading to serious injuries. Store away from kids and pets.

Fire warning

Dust created during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Pacemakers

Individuals with a pacemaker have to keep an safe separation from magnets. The magnetic field can stop the functioning of the implant.

Thermal limits

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