Grip strength weakens sharply per each millimeter of gap. Note that every additional insulation layer (e.g., dirt, paint, veneer) noticeably reduces the pull force. Magnets work optimally during direct contact; gap drastically cuts the force. Observe how flashily the pull force fall, when the magnet does not touch directly to the metal substrate. When planning the mounting, eliminate additional spacers.

When hanging a holder on a upright surface (e.g., a car body), it you can count on barely about 1/5 of nominal attraction strength. Gravity and a low friction coefficient mean that holders slip easier than they pop off the substrate. Planning a wall mount? Remember that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the holder will slip down under a noticeably lighter load. Utilizing a rubberized pad can effectively increase the grip.

A thin sheet cannot take in the entire magnetic field, which squanders power of the holder. If you install a neodymium to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To achieve 100% of this neodymium's power, you require a sufficiently solid element of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product shows lower pull force. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently damage this product. As the temperature rises, the neodymium's force briefly drops. Refrain from using this magnet close to ovens higher than its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetism.
*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. The connection of two magnets generates a stronger field and a further horizon of performance. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the pinch force is huge. The repulsion force is a bit weaker than the connection force, but still large.
*Field value between like poles reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Results refer to shear force of two matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a large risk to electronics as well as medical implants. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can cause material chips or painful pinches to skin. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when handling with large magnets.

*Caution: On a vertical surface, the magnet holds just ~20% of its nominal pull.

2. Plate thickness effect

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

*For N38 material, the safety limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (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 Pc (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 Pc 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.

Model MPL 40x10x5x2[7/3.5] / N38 features a flat shape and professional pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 116.27 N is ready for shipment in 24h, allowing for rapid realization of your project. 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 40x10x5x2[7/3.5] / 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.
They constitute a key element in the production of generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for workshop organization 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 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. In practice, this means that this magnet has the greatest attraction force on its main planes (40x10 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 40x10x5 mm, which, at a weight of 15 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 11.85 kg (force ~116.27 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:
  • They do not lose magnetism, even after nearly 10 years – the decrease in power is only ~1% (based on measurements),
  • Neodymium magnets are characterized by highly resistant to loss of magnetic properties caused by external magnetic fields,
  • Thanks to the glossy finish, the plating of nickel, gold-plated, or silver gives an elegant appearance,
  • Neodymium magnets generate maximum magnetic induction on a their surface, which allows for strong attraction,
  • 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...
  • Possibility of custom shaping as well as optimizing to individual requirements,
  • Universal use in modern industrial fields – they are used in HDD drives, motor assemblies, diagnostic systems, as well as other advanced devices.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

What to avoid - cons of neodymium magnets and proposals for their use:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
  • Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 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, in case of application outdoors
  • Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic holder.
  • Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Highest magnetic holding force – what affects it?

Information about lifting capacity was determined for the most favorable conditions, assuming:
  • with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • with a surface perfectly flat
  • under conditions of no distance (surface-to-surface)
  • during pulling in a direction perpendicular to the mounting surface
  • at room temperature

Lifting capacity in practice – influencing factors

During everyday use, the actual lifting capacity results from many variables, listed from most significant:
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
  • Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
  • Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets
Sensitization to coating

Certain individuals suffer from a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Frequent touching may cause dermatitis. We suggest use safety gloves.

Machining danger

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Powerful field

Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.

Heat warning

Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and strength.

Life threat

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

Crushing risk

Big blocks can break fingers instantly. Do not put your hand betwixt two attracting surfaces.

GPS and phone interference

Be aware: rare earth magnets produce a field that confuses precision electronics. Maintain a separation from your mobile, tablet, and GPS.

Magnet fragility

NdFeB magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them shattering into small pieces.

Magnetic media

Device Safety: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).

This is not a toy

Absolutely keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are very dangerous.
