Magnetic force drops significantly per each millimeter of gap. Keep in mind that even the smallest gap (e.g., contamination, paint, veneer) significantly diminishes the holding power. Magnets operate strongest during direct contact; gap kills the power. Notice how quickly the pull force fall, when the magnet does not touch directly to the steel surface. When planning the assembly, eliminate redundant distances.

The following data calculates the theoretical force necessary to initiate the slippage of the magnet downwards against a upright steel wall (assuming standard friction). The holding force varies with the gap size between the magnet and the surface.

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

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	5.86 kg / 12.92 pounds 5859.0 g / 57.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.91 kg / 8.61 pounds 3906.0 g / 38.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.95 kg / 4.31 pounds 1953.0 g / 19.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	9.77 kg / 21.53 pounds 9765.0 g / 95.8 N

When placing a magnet on a upright plane (e.g., a fridge), it you can count on only about 1/5 of its nominal power. Gravity and a weak degree of grip influence the fact that magnets move down easier than they detach. Designing a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a significantly smaller load. Utilizing a rubberized pad can significantly increase the grip.

A too thin steel is unable to take in the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To utilize full efficiency of this magnet's potential, you need a suitably thick piece of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the holder works worse. We suggest choosing the steel dimension from these parameters.

Classic neodymiums lose power past the thermal threshold. Protect against heat – excessive heat can irreversibly damage this product. With increasing heat, the magnet's power momentarily lowers. Avoid using this magnet close to ovens exceeding its safe range. Too high temperature will cause destruction of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) may lose charge permanently sooner than long magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a strong closure? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the collision energy is extreme. The levitation is a bit weaker than the attraction, but still large.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
Important: Calculations apply to friction force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a large risk to electronics as well as medical implants. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a violent impact against metal risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when playing with powerful specimens.

Corrosion warning: 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. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical wall, the magnet holds only a fraction of its nominal pull.

2. Plate thickness effect

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.46

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.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 30x20x10 mm and a weight of 45 g, guarantees the highest quality connection. This rectangular block with a force of 191.55 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting 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. To separate the MPL 30x20x10 / 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 30x20x10 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 30x20x10 / 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. Remember to roughen and wash 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 (30x20 mm), which is ideal for flat mounting. 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), 20 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 30x20x10 mm and a self-weight of 45 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Benefits

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets remain extremely resistant to magnetic field loss caused by external field sources,
By applying a decorative coating of silver, the element acquires an elegant look,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to modularity in shaping and the capacity to adapt to client solutions,
Significant place in electronics industry – they serve a role in magnetic memories, electromotive mechanisms, diagnostic systems, also other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and 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 strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these magnets are able to complicate diagnosis medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

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

The load parameter shown refers to the maximum value, obtained under laboratory conditions, meaning:

on a plate made of structural steel, effectively closing the magnetic flux
with a cross-section no less than 10 mm
with an ground touching surface
without any air gap between the magnet and steel
under axial force vector (90-degree angle)
at ambient temperature room level

Determinants of practical lifting force of a magnet

In real-world applications, the real power is determined by several key aspects, listed from the most important:

Gap (betwixt the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the power to be escaped to the other side.
Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.

Warnings

Do not drill into magnets

Dust produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Beware of splinters

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

Heat sensitivity

Control the heat. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.

Immense force

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.

Danger to pacemakers

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Skin irritation risks

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.

GPS Danger

Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.

Serious injuries

Protect your hands. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!

Magnetic media

Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
