Pulling power drops significantly with every subsequent millimeter of gap. Note that even a very thin break (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnets work strongest at the point of direct contact; distance weakens the force. Analyze how flashily the parameters plummet, when the magnet does not touch tightly to the steel surface. When planning the mounting, eliminate redundant distances.

This section shows the theoretical weight limit necessary to start the slippage of the magnet downwards along a upright steel plate (considering standard friction). This value is a function of the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 15x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.27 kg / 2.79 pounds 1266.0 g / 12.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.84 kg / 1.86 pounds 844.0 g / 8.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.42 kg / 0.93 pounds 422.0 g / 4.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.11 kg / 4.65 pounds 2110.0 g / 20.7 N

When hanging a magnet on a vertical wall (e.g., a fridge), it will only hold just about 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient cause that products slip easier than they detach. Want to create a wall mount? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a noticeably lighter load. Utilizing a rubberized pad can significantly increase the grip.

3 mm	75%	3.17 kg / 6.98 pounds 3165.0 g / 31.0 N
5 mm	100%	4.22 kg / 9.30 pounds 4220.0 g / 41.4 N
10 mm	100%	4.22 kg / 9.30 pounds 4220.0 g / 41.4 N
11 mm	100%	4.22 kg / 9.30 pounds 4220.0 g / 41.4 N
12 mm	100%	4.22 kg / 9.30 pounds 4220.0 g / 41.4 N

A too thin steel is unable to absorb the entire magnetic field, which squanders power of the magnet. Should you mount a strong magnet to a too thin substrate, the field will pass right through and the pull force will drop sharply. To squeeze 100% of this neodymium's power, you need a suitably thick piece of metal. The material oversaturation causes that on thin elements (e.g., appliance housings), the product works worse. We suggest choosing the steel thickness based on the following data.

Table 5: Thermal resistance (material behavior) - resistance threshold
MW 15x4 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	4.22 kg / 9.30 pounds 4220.0 g / 41.4 N	OK
40 °C	-2.2%	4.13 kg / 9.10 pounds 4127.2 g / 40.5 N	OK
60 °C	-4.4%	4.03 kg / 8.89 pounds 4034.3 g / 39.6 N
80 °C	-6.6%	3.94 kg / 8.69 pounds 3941.5 g / 38.7 N
100 °C	-28.8%	3.00 kg / 6.62 pounds 3004.6 g / 29.5 N

Standard neodymium magnets lose strength above the temperature limit. Watch out for overheating – heat can permanently demagnetize this product. With increasing heat, the magnet's power temporarily decreases. Avoid using this product near heat sources exceeding its operating temperature limit. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet setup. The connection of two magnets generates a stronger field and a further horizon of action. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the impact force is massive. The levitation is marginally weaker than the attraction, but still large.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
* Results show sliding force of two same magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a large risk to electronic devices and medical implants. These neodymiums generate a field that prevents correct functioning of digital equipment. Notice: the unseen radiation passes through tissues and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are delicate – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

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

1. Vertical hold

*Note: On a vertical surface, the magnet retains just approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

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

3. Heat tolerance

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.37

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.

The presented product is an extremely powerful rod magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø15x4 mm, guarantees optimal power. The MW 15x4 / N38 component is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 4.22 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 41.38 N with a weight of only 5.3 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø15x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø15x4 mm, which, at a weight of 5.3 g, makes it an element with impressive magnetic energy density. The value of 41.38 N means that the magnet is capable of holding a weight many times exceeding its own mass of 5.3 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 15 mm. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They retain magnetic properties for around 10 years – the drop is just ~1% (based on simulations),
They are resistant to demagnetization induced by external magnetic fields,
A magnet with a smooth nickel surface has an effective appearance,
The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Considering the potential of precise molding and customization to individualized requirements, magnetic components can be created in a broad palette of forms and dimensions, which expands the range of possible applications,
Huge importance in high-tech industry – they serve a role in mass storage devices, drive modules, diagnostic systems, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions

Weaknesses

Cons of neodymium magnets: application proposals

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complicated forms in magnets, we recommend using cover - magnetic holder.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Detachment force of the magnet in optimal conditions – what affects it?

The load parameter shown represents the peak performance, measured under laboratory conditions, meaning:

using a base made of high-permeability steel, functioning as a circuit closing element
with a cross-section minimum 10 mm
with an ground contact surface
with direct contact (no paint)
under perpendicular application of breakaway force (90-degree angle)
in neutral thermal conditions

Practical aspects of lifting capacity – factors

Holding efficiency is affected by working environment parameters, such as (from priority):

Gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, rust or debris).
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material composition – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.

Warnings

Cards and drives

Equipment safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).

Shattering risk

Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.

Respect the power

Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.

Dust explosion hazard

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

Precision electronics

Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.

Crushing risk

Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Permanent damage

Avoid heat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).

Avoid contact if allergic

A percentage of the population have a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to skin redness. We strongly advise use safety gloves.

Keep away from children

Always keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.

Warning for heart patients

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
