Grip strength weakens significantly per each millimeter of distance. Note that even the smallest gap (e.g., dirt, varnish, rust) noticeably diminishes the holding power. Magnets hold strongest at the point of direct contact; distance nullifies the force. See how rapidly the pull force drop, when the magnet does not adhere flatly to the metal substrate. When calculating the arrangement, eliminate redundant distances.

This section defines the estimated holding capacity needed to initiate the downward movement of the magnet down along a vertical steel plate (assuming standard friction). This parameter depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 5x7 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.20 kg / 0.44 lbs 201.0 g / 2.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.13 kg / 0.30 lbs 134.0 g / 1.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.15 lbs 67.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.34 kg / 0.74 lbs 335.0 g / 3.3 N

When hanging a magnet on a vertical wall (e.g., a fridge), it will only hold barely about 1/5 of its maximum pull force. Gravity as well as a weak degree of grip cause that holders slide down faster than they detach. Want to create a wall mount? Note that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the holder will give way down under a much lighter weight. Utilizing a rubberized pad can effectively improve the result.

12 mm	100%	0.67 kg / 1.48 lbs 670.0 g / 6.6 N

A thin metal plate is not enough to absorb the entire magnetic field, which wastes potential of the magnet. If you install a neodymium to a thin surface, the flux will pass right through and the pull force will drop sharply. To achieve full efficiency of this magnet's potential, you require a sufficiently solid piece of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the magnet holds weaker. We suggest choosing the steel cross-section based on the following data.

Table 5: Thermal stability (material behavior) - thermal limit
MW 5x7 / N38

Ordinary NdFeB products lose power past the thermal threshold. Protect against heat – heat can permanently destroy this magnet. With increasing heat, the neodymium's capacity briefly drops. Avoid using this magnet in hot environments exceeding its working range. Ignoring the limit will cause permanent loss of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnets interact from a much further distance than a magnet and steel combination. The setup of magnet-to-magnet produces a massive flux and a larger range of operation. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is huge. The repulsion force is a bit weaker than the connection force, but still large.
*Field value for N-N configuration drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Important: Results apply to friction force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a field that disrupts operation of digital equipment. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - warning
MW 5x7 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	25.73 km/h (7.15 m/s)	0.03 J

100 mm	81.34 km/h (22.59 m/s)	0.26 J

Magnetic elements are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when handling with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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

1. Vertical hold

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

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) drastically limits the holding force.

3. Power loss vs temp

*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) = 1.05

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.

MW 12x50 / N38 - cylindrical magnet

28.29 ZŁ brutto / pcs

The presented product is an extremely powerful cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø5x7 mm, guarantees optimal power. The MW 5x7 / N38 model is characterized by high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.67 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 6.60 N with a weight of only 1.03 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 5.1 mm) using two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø5x7), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø5x7 mm, which, at a weight of 1.03 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.67 kg (force ~6.60 N), which, with such compact dimensions, proves the high grade of the NdFeB material. 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 5 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.

Strengths and weaknesses of rare earth magnets.

Benefits

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

Their magnetic field remains stable, and after approximately 10 years it decreases only by ~1% (according to research),
They maintain their magnetic properties even under external field action,
By applying a decorative coating of silver, the element gains an proper look,
The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
In view of the option of flexible shaping and customization to unique needs, magnetic components can be modeled in a variety of geometric configurations, which makes them more universal,
Versatile presence in modern industrial fields – they find application in mass storage devices, electromotive mechanisms, diagnostic systems, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complex shapes in magnets, we propose using cover - magnetic mechanism.
Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products are able to disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what affects it?

The load parameter shown represents the maximum value, obtained under ideal test conditions, specifically:

using a sheet made of mild steel, acting as a ideal flux conductor
whose transverse dimension equals approx. 10 mm
with an polished touching surface
under conditions of gap-free contact (metal-to-metal)
during pulling in a direction vertical to the plane
at standard ambient temperature

Magnet lifting force in use – key factors

Holding efficiency is influenced by working environment parameters, mainly (from most important):

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and holding force.
Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.

Precautions when working with neodymium magnets

Phone sensors

An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to avoid damaging the sensors.

Beware of splinters

NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them shattering into small pieces.

Nickel allergy

Certain individuals experience a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause an allergic reaction. We strongly advise use safety gloves.

Crushing force

Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Heat sensitivity

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Handling guide

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Cards and drives

Do not bring magnets close to a wallet, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.

Medical interference

Individuals with a ICD must keep an absolute distance from magnets. The magnetic field can stop the operation of the implant.

Choking Hazard

Always keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.

Mechanical processing

Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
