Magnetic force weakens sharply with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Magnetic products work strongest in perfect adhesion; air break nullifies the force. See how rapidly the pull force fall, when the product does not touch flatly to the steel surface. When calculating the arrangement, avoid redundant distances.

The table below indicates the approximate holding capacity sufficient to start the shifting of the magnet down against a vertical steel plate (considering standard friction). This parameter varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 45x35 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	20.69 kg / 45.62 pounds 20694.0 g / 203.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	13.80 kg / 30.41 pounds 13796.0 g / 135.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	6.90 kg / 15.21 pounds 6898.0 g / 67.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	34.49 kg / 76.04 pounds 34490.0 g / 338.3 N

When hanging a holder on a vertical surface (e.g., a fridge), it will maintain barely about 1/5 of nominal attraction strength. Gravity and a weak degree of grip mean that magnets move down easier than they pull off. Designing a vertical fastening? Note that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will slip down under a much lighter load. Using a rubber layer can significantly improve the result.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 45x35 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	3%	2.30 kg / 5.07 pounds 2299.3 g / 22.6 N
1 mm	8%	5.75 kg / 12.67 pounds 5748.3 g / 56.4 N
2 mm	17%	11.50 kg / 25.35 pounds 11496.7 g / 112.8 N
3 mm	25%	17.25 kg / 38.02 pounds 17245.0 g / 169.2 N
5 mm	42%	28.74 kg / 63.36 pounds 28741.7 g / 282.0 N
10 mm	83%	57.48 kg / 126.73 pounds 57483.3 g / 563.9 N
11 mm	92%	63.23 kg / 139.40 pounds 63231.7 g / 620.3 N
12 mm	100%	68.98 kg / 152.07 pounds 68980.0 g / 676.7 N

A thin sheet is incapable of conduct 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 holding will be smaller. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid backing of metal. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We recommend selecting the steel cross-section from these parameters.

Classic neodymiums irreversibly lose strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this product. With increasing heat, the neodymium's power momentarily decreases. Do not use this magnet in hot environments higher than its safe range. Too high temperature will cause irreversible degradation of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) may lose charge permanently sooner than taller cylinders. Red status in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet combination. The setup of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still large.
*Flux density between like poles is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Estimates refer to sliding force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures
MW 45x35 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	26.5 cm
Hearing aid	10 Gs (1.0 mT)	20.5 cm
Mechanical watch	20 Gs (2.0 mT)	16.0 cm

Payment card	400 Gs (40.0 mT)	5.0 cm
HDD hard drive	600 Gs (60.0 mT)	4.0 cm

Powerful magnet radiation is a large risk to IT equipment and pacemakers. These magnets produce a field that destroys function of digital equipment. Be aware: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 45x35 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	15.46 km/h (4.29 m/s)	3.85 J
30 mm	22.87 km/h (6.35 m/s)	8.42 J
50 mm	29.06 km/h (8.07 m/s)	13.61 J
100 mm	41.00 km/h (11.39 m/s)	27.07 J

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or injury to fingers. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Caution: On a vertical surface, the magnet holds just ~20% of its max power.

2. Steel thickness impact

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

3. Power loss vs temp

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.78

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.

The presented product is an extremely powerful rod magnet, produced from advanced NdFeB material, which, with dimensions of Ø45x35 mm, guarantees the highest energy density. The MW 45x35 / N38 component is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 68.98 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, 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 created for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 676.73 N with a weight of only 417.49 g, this rod is indispensable in miniature devices and wherever every gram matters.

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

Magnets NdFeB grade N38 are strong enough for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø45x35), 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 Ø45x35 mm, which, at a weight of 417.49 g, makes it an element with high magnetic energy density. The value of 676.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 417.49 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 35 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 through the diameter if your project requires it.

Advantages as well as disadvantages of neodymium magnets.

Pros

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

Their magnetic field is maintained, and after around 10 years it decreases only by ~1% (according to research),
Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by magnetic disturbances,
By applying a lustrous layer of gold, the element acquires an aesthetic look,
They are known for high magnetic induction at the operating surface, making them more effective,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in shaping and the capacity to customize to unusual requirements,
Huge importance in future technologies – they are commonly used in mass storage devices, electric drive systems, diagnostic systems, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in miniature devices

Weaknesses

Disadvantages of neodymium magnets:

At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
We recommend cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Highest magnetic holding force – what affects it?

Information about lifting capacity was defined for ideal contact conditions, assuming:

using a sheet made of mild steel, acting as a ideal flux conductor
whose transverse dimension is min. 10 mm
characterized by smoothness
under conditions of no distance (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
at room temperature

Determinants of lifting force in real conditions

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

Air gap (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.

Warnings

Magnetic interference

GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.

Heat sensitivity

Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.

Cards and drives

Avoid bringing magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Material brittleness

Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them breaking into shards.

Product not for children

Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.

Fire risk

Dust generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Conscious usage

Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.

Serious injuries

Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Implant safety

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Metal Allergy

Certain individuals have a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Extended handling may cause dermatitis. We suggest use safety gloves.
