Grip strength decreases sharply with every subsequent millimeter of distance. Keep in mind that even a very thin break (e.g., contamination, varnish, veneer) strongly weakens the grip. Magnets operate most effectively at the point of direct contact; air break weakens the power. Observe how quickly the parameters fall, when the product does not touch flatly to the steel surface. When designing the arrangement, eliminate additional spacers.

This section presents the estimated holding capacity required to start the slippage of the magnet vertically along a vertical metal surface (assuming typical friction coefficient). This value varies with the air gap between the magnet and the metal.

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

Raw steel	µ = 0.3 30% Nominalnej Siły	0.48 kg / 1.06 pounds 480.0 g / 4.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.32 kg / 0.71 pounds 320.0 g / 3.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.16 kg / 0.35 pounds 160.0 g / 1.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.80 kg / 1.76 pounds 800.0 g / 7.8 N

When placing a holder on a vertical surface (e.g., a fridge), it will only hold barely approx. 1/5 of its nominal power. Gravity and a weak degree of grip influence the fact that products move down easier than they detach. Designing a vertical fastening? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter cargo. Application of an anti-slip layer can significantly increase the grip.

A thin metal plate is unable to focus the full magnetic flux, which squanders power of the holder. Should you install a neodymium to a thin surface, the flux will pass right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you require a sufficiently solid element of metal. The saturation phenomenon means that on delicate walls (e.g., car bodies), the holder shows lower pull force. We advise picking the steel cross-section based on the following data.

Ordinary NdFeB products irreversibly lose strength past the thermal threshold. Avoid high temperatures – heat can permanently demagnetize this magnet. With every degree above norm, the magnet's power momentarily drops. Do not use this magnet close to ovens higher than its safe range. Too high temperature will result in permanent loss of magnetism.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently sooner than taller cylinders. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal setup. The setup of magnet-to-magnet produces a massive flux and a larger range of operation. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
* Estimates show sliding force of dual same magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a serious hazard to electronic devices and pacemakers. These magnets generate a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

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

2. Steel thickness impact

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

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.48

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.

Component MPL 7x7x3 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 1.60 kg), this product is available immediately from our warehouse in Poland. 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. Watch your fingers! Magnets with a force of 1.60 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.

Plate magnets MPL 7x7x3 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 1.60 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. 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 7x7x3 / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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 (7x7 mm), which is ideal for flat mounting. 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: 7 mm (length), 7 mm (width), and 3 mm (thickness). It is a magnetic block with dimensions 7x7x3 mm and a self-weight of 1.1 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of rare earth magnets.

Strengths

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

They do not lose magnetism, even after approximately ten years – the decrease in strength is only ~1% (based on measurements),
They feature excellent resistance to magnetism drop when exposed to external magnetic sources,
The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
Due to the option of precise shaping and customization to custom needs, NdFeB magnets can be modeled in a broad palette of geometric configurations, which makes them more universal,
Universal use in future technologies – they serve a role in hard drives, brushless drives, medical equipment, as well as technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of NdFeB magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in power. 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
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated forms.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
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

Magnetic strength at its maximum – what it depends on?

Holding force of 1.60 kg is a result of laboratory testing conducted under the following configuration:

on a block made of structural steel, effectively closing the magnetic flux
possessing a thickness of at least 10 mm to ensure full flux closure
with an ground touching surface
under conditions of no distance (surface-to-surface)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Determinants of lifting force in real conditions

Bear in mind that the magnet holding may be lower influenced by elements below, in order of importance:

Clearance – existence of any layer (paint, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets

Beware of splinters

NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them breaking into small pieces.

Threat to navigation

Be aware: neodymium magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, device, and GPS.

Mechanical processing

Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Powerful field

Handle magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their power.

Pinching danger

Danger of trauma: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Keep away from children

Always store magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.

Heat sensitivity

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

Warning for heart patients

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Allergy Warning

Certain individuals experience a sensitization to Ni, which is the common plating for NdFeB magnets. Prolonged contact might lead to a rash. It is best to use safety gloves.

Threat to electronics

Avoid bringing magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
