Grip strength drops sharply with every mm of spacing. Remember that every additional insulation layer (e.g., dirt, varnish, veneer) noticeably weakens the grip. Neodymiums work optimally in perfect adhesion; air break drastically cuts the force. Analyze how flashily the pull force fall, when the magnet does not touch tightly to the metal substrate. When designing the mounting, discard unnecessary gaps.

The table below shows the theoretical force necessary to cause the shifting of the magnet downwards on a upright metal surface (considering standard friction). This parameter depends on the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 30x15x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.63 kg / 1.40 LBS 633.0 g / 6.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.42 kg / 0.93 LBS 422.0 g / 4.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.21 kg / 0.47 LBS 211.0 g / 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.06 kg / 2.33 LBS 1055.0 g / 10.3 N

When hanging a holder on a upright surface (e.g., a board), it you can count on just about 1/5 of nominal attraction strength. Gravity and a weak degree of grip influence the fact that holders move down faster than they pop off the substrate. Want to create a vertical fastening? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter weight. Application of an anti-slip layer can effectively improve the result.

12 mm	100%	2.11 kg / 4.65 LBS 2110.0 g / 20.7 N

A too thin steel is incapable of focus the entire magnetic field, which weakens actual performance of the magnet. If you install a neodymium to a weak sheet, the flux will penetrate right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you need a suitably thick backing of metal. The material oversaturation causes that on thin elements (e.g., appliance housings), the magnet works worse. We suggest choosing the steel dimension according to the table below.

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. With every degree above norm, the magnet's power momentarily decreases. Avoid using this product near heat sources exceeding its working range. Too high temperature will cause irreversible degradation of magnetism.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) risk losing magnetic properties under lower heat stress than taller cylinders. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a much further distance than a neodymium and metal setup. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is marginally weaker than the connection force, but still large.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Figures apply to sliding force of two same magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a real danger to electronic devices as well as pacemakers. These neodymiums produce a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and glass. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when handling with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains merely ~20% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly limits 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) = 0.13

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.

Model MPL 30x15x2 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 20.69 N is ready for shipment in 24h, allowing for rapid realization of your project. 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. To separate the MPL 30x15x2 / 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 30x15x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 2.11 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. 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.

Standardly, the MPL 30x15x2 / N38 model is magnetized through the thickness (dimension 2 mm), which means that the N and S poles are located on its largest, flat surfaces. 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), 15 mm (width), and 2 mm (thickness). It is a magnetic block with dimensions 30x15x2 mm and a self-weight of 6.75 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Pros

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

They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
They have excellent resistance to magnetic field loss due to opposing magnetic fields,
The use of an metallic layer 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 extremely 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 accurate forming as well as modifying to individual applications,
Versatile presence in innovative solutions – they serve a role in computer drives, electric drive systems, diagnostic systems, and complex engineering applications.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Characteristics of disadvantages of neodymium magnets and proposals for their use:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Due to limitations in creating nuts and complicated forms in magnets, we recommend using a housing - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these products can disrupt the diagnostic process medical in case of swallowing.
With budget limitations the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum magnetic pulling force – what affects it?

The declared magnet strength represents the limit force, recorded under optimal environment, meaning:

on a base made of structural steel, effectively closing the magnetic field
with a cross-section no less than 10 mm
with an polished contact surface
with direct contact (no impurities)
for force acting at a right angle (in the magnet axis)
in neutral thermal conditions

Impact of factors on magnetic holding capacity in practice

It is worth knowing that the magnet holding may be lower subject to the following factors, in order of importance:

Distance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be escaped to the other side.
Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings

Danger to pacemakers

Individuals with a pacemaker must maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Avoid contact if allergic

A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Extended handling can result in dermatitis. We suggest use safety gloves.

Combustion hazard

Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Demagnetization risk

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Magnet fragility

Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Bodily injuries

Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Powerful field

Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often quicker than you can move away.

Precision electronics

Remember: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, tablet, and GPS.

This is not a toy

Only for adults. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of children and animals.

Cards and drives

Do not bring magnets near a purse, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
