Magnetic force drops significantly with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., contamination, varnish, veneer) noticeably weakens the grip. Magnets hold strongest during direct contact; distance weakens the power. Analyze how flashily the load capacity plummet, when the product does not touch directly to the steel surface. When calculating the arrangement, discard additional spacers.

The table below defines the approximate weight limit sufficient to initiate the sliding of the magnet down along a vertical metal surface (assuming standard friction). The holding force depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.11 kg / 0.25 lbs 112.0 g / 1.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.06 kg / 0.12 lbs 56.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.28 kg / 0.62 lbs 280.0 g / 2.7 N

When placing a holder on a upright surface (e.g., a board), it will maintain just about 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient cause that magnets slide down easier than they pop off the substrate. Designing a hanger? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a significantly smaller load. Utilizing a rubberized layer can drastically improve the result.

A too thin steel is unable to focus the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To utilize the maximum of this magnet's power, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., appliance housings), the product shows lower pull force. We advise picking the steel cross-section from these parameters.

Ordinary NdFeB products change their properties strength above the temperature limit. Watch out for overheating – high temperature can permanently damage this magnet. As the temperature rises, the neodymium's capacity temporarily lowers. Do not use this magnet in hot environments higher than its safe range. Ignoring the limit will cause permanent loss of magnetic properties.

*Technical advisory: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The setup of two magnets creates a more powerful interaction and a wider radius of operation. Want to build a solid fastener? Apply two magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the pinch force is massive. The repulsion force is slightly lower than the attraction, but still significant.
*The magnetic induction between like poles drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Results refer to friction force of dual matching magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to electronics as well as medical implants. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when handling with large magnets.

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

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.10

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 20x10x1 / N38 features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 0.56 kg), this product is available off-the-shelf 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 strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 20x10x1 / 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. 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 generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 20x10x1 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 10 mm (width), and 1 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 0.56 kg (force ~5.46 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Advantages

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
Magnets perfectly protect themselves against loss of magnetization caused by foreign field sources,
By using a shiny coating of gold, the element has an modern look,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to modularity in forming and the ability to customize to complex applications,
Wide application in advanced technology sectors – they serve a role in data components, motor assemblies, diagnostic systems, and multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
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
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic holder.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets are able to complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is higher than average,

Pull force analysis

Maximum lifting force for a neodymium magnet – what it depends on?

Information about lifting capacity was determined for ideal contact conditions, taking into account:

on a plate made of structural steel, perfectly concentrating the magnetic flux
possessing a massiveness of at least 10 mm to ensure full flux closure
with an polished contact surface
without any insulating layer between the magnet and steel
during pulling in a direction vertical to the mounting surface
at room temperature

What influences lifting capacity in practice

Bear in mind that the application force will differ depending on elements below, starting with the most relevant:

Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Keep away from electronics

An intense magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.

This is not a toy

Always store magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.

Machining danger

Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Safe operation

Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.

Protect data

Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

Maximum temperature

Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.

Crushing force

Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.

Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness happens, cease working with magnets and use protective gear.

Medical implants

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Magnet fragility

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets will cause them shattering into small pieces.

Caution! Learn more about hazards in the article: Magnet Safety Guide.
