Pulling power drops significantly with every mm of distance. Remember that even a very thin break (e.g., dirt, varnish, rust) strongly weakens the grip. Neodymiums hold optimally during direct contact; distance weakens the power. Analyze how flashily the load capacity plummet, when the magnet does not touch tightly to the metal substrate. When designing the arrangement, discard redundant distances.

The table below calculates the theoretical shear load necessary to initiate the slippage of the magnet down against a vertical steel wall (considering standard friction). The holding force varies with the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 30x20x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.66 kg / 5.86 LBS 2658.0 g / 26.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.77 kg / 3.91 LBS 1772.0 g / 17.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.89 kg / 1.95 LBS 886.0 g / 8.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.43 kg / 9.77 LBS 4430.0 g / 43.5 N

When mounting a element on a upright surface (e.g., a car body), it you can count on only approx. 20%-30% of its nominal power. Gravity and a low friction coefficient cause that products slide down faster than they pull off. Planning a vertical fastening? Note that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the element will slide down under a much lighter cargo. Application of an anti-slip coating can drastically increase the grip.

A thin sheet is incapable of focus the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize 100% of this neodymium's power, you require a sufficiently solid backing of metal. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel thickness according to the table below.

Standard neodymium magnets lose strength after exceeding the maximum temperature. Protect against heat – high temperature can permanently destroy this magnet. With every degree above norm, the neodymium's power temporarily drops. Do not use this magnet close to ovens higher than its safe range. Exceeding the critical threshold will result in permanent loss of magnetism.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and sheet combination. The setup of magnet-to-magnet generates a stronger field and a further horizon of operation. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is massive. The levitation is marginally weaker than the attraction, but still significant.
*Field value in repulsion mode is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Results show sliding force of two matching magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a real danger to IT equipment as well as medical implants. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can destroy the magnet or painful pinches to fingers. Always hold the magnet during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. 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.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Caution: On a vertical wall, the magnet retains just a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 30x20x5 mm and a weight of 22.5 g, guarantees the highest quality connection. As a block magnet with high power (approx. 8.86 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. Watch your fingers! Magnets with a force of 8.86 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 30x20x5 / 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. 8.86 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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. 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: 30 mm (length), 20 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 30x20x5 mm and a self-weight of 22.5 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their exceptional pulling force, neodymium magnets offer the following advantages:

They do not lose power, even over nearly ten years – the drop in lifting capacity is only ~1% (according to tests),
Magnets effectively resist against loss of magnetization caused by foreign field sources,
A magnet with a shiny nickel surface has better aesthetics,
They show high magnetic induction at the operating surface, making them more effective,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
Thanks to flexibility in forming and the ability to customize to specific needs,
Wide application in high-tech industry – they are utilized in mass storage devices, drive modules, 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 crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited ability of creating nuts in the magnet and complex shapes - recommended is casing - magnet mounting.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
Due to neodymium price, their price is higher than average,

Pull force analysis

Magnetic strength at its maximum – what contributes to it?

The load parameter shown concerns the peak performance, measured under ideal test conditions, meaning:

with the use of a sheet made of low-carbon steel, guaranteeing maximum field concentration
with a cross-section no less than 10 mm
with an ground touching surface
under conditions of ideal adhesion (metal-to-metal)
under vertical force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Bear in mind that the application force will differ subject to the following factors, starting with the most relevant:

Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.

H&S for magnets

Safe operation

Handle magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their force.

Skin irritation risks

It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, prevent direct skin contact and select coated magnets.

Dust is flammable

Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.

Maximum temperature

Keep cool. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).

Beware of splinters

Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Hand protection

Big blocks can break fingers instantly. Do not place your hand between two attracting surfaces.

Product not for children

Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep away from kids and pets.

Keep away from electronics

Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Medical implants

For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Threat to electronics

Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Caution! Details about risks in the article: Magnet Safety Guide.
