Pulling power drops drastically with every subsequent millimeter of gap. Note that even a microscopic distance (e.g., dirt, paint, rust) strongly weakens the grip. Magnetic products operate optimally at the point of direct contact; gap nullifies the force. Analyze how quickly the load capacity drop, when the magnet does not adhere flatly to the metal substrate. When calculating the assembly, discard unnecessary gaps.

The following data defines the theoretical shear load necessary to start the downward movement of the magnet vertically on a vertical metal surface (considering standard friction). This parameter is a function of the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - 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 pounds 201.0 g / 2.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.13 kg / 0.30 pounds 134.0 g / 1.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.15 pounds 67.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.34 kg / 0.74 pounds 335.0 g / 3.3 N

When placing a holder on a vertical plane (e.g., a car body), it will only hold barely approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient cause that holders slip easier than they detach. Planning a hanger? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a noticeably lighter weight. Application of an anti-slip coating can significantly raise the stability.

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

A thin metal plate is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this magnet's power, you require a sufficiently solid piece of metal. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the product works worse. We suggest choosing the steel dimension according to the table below.

Table 5: Thermal stability (stability) - thermal limit

100 °C	-28.8%	0.48 kg / 1.05 pounds 477.0 g / 4.7 N

Ordinary NdFeB products lose parameters past the thermal threshold. Avoid high temperatures – high temperature can permanently damage this product. As the temperature rises, the magnet's power temporarily drops. Refrain from using this magnet near heat sources higher than its working range. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) risk losing magnetic properties sooner than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a further horizon of action. Want to build a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is massive. The repulsion force is marginally weaker than the connection force, but still significant.
*Field value in repulsion mode is approximately ~0 Gs in the exact middle of the gap (resulting from vector opposition).
* Results apply to friction force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to electronics as well as pacemakers. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 5x7 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	25.73 km/h (7.15 m/s)	0.03 J
30 mm	44.55 km/h (12.38 m/s)	0.08 J
50 mm	57.52 km/h (15.98 m/s)	0.13 J
100 mm	81.34 km/h (22.59 m/s)	0.26 J

Magnetic elements are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when working with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits the holding force.

3. Temperature resistance

*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) = 1.05

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 incredibly powerful cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø5x7 mm, guarantees maximum efficiency. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.67 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient filters, 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 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 precision component. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø5x7), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 7 mm. 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 power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, 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. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Advantages as well as disadvantages of neodymium magnets.

Strengths

Apart from their superior power, neodymium magnets have these key benefits:

They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
Neodymium magnets are remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
A magnet with a metallic gold surface has better aesthetics,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of individual shaping and adapting to complex requirements,
Universal use in modern industrial fields – they are commonly used in magnetic memories, motor assemblies, medical devices, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems

Limitations

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can crack, therefore we recommend 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 strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
Limited possibility of making threads in the magnet and complicated shapes - preferred is cover - magnet mounting.
Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The lifting capacity listed is a measurement result executed under specific, ideal conditions:

on a plate made of structural steel, optimally conducting the magnetic field
with a cross-section minimum 10 mm
with a surface free of scratches
under conditions of gap-free contact (surface-to-surface)
during detachment in a direction vertical to the plane
at room temperature

What influences lifting capacity in practice

Real force impacted by specific conditions, such as (from most important):

Distance (betwixt the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or debris).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be lost into the air.
Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.

Safe handling of NdFeB magnets

Danger to pacemakers

For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.

Caution required

Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often faster than you can react.

Combustion hazard

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

Electronic hazard

Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Permanent damage

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

Pinching danger

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

No play value

Adult use only. Small elements pose a choking risk, leading to severe trauma. Store away from children and animals.

Compass and GPS

An intense magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Nickel allergy

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.

Magnet fragility

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
