50 mm	1 Gs 0.1 mT	0.00 kg / 0.00 lbs 0.0 g / 0.0 N	weak grip

Grip strength weakens sharply with every mm of gap. Keep in mind that even the smallest gap (e.g., dirt, paint, dust) significantly reduces the pull force. Magnets work optimally at the point of direct contact; air break nullifies the force. Notice how flashily the parameters drop, when the magnet does not touch flatly to the metal substrate. When calculating the mounting, avoid redundant distances.

Table 2: Slippage force (wall)
MW 7x2 / N38

50 mm	Stal (~0.2)	0.00 kg / 0.00 lbs 0.0 g / 0.0 N

The table below defines the approximate weight limit necessary to initiate the shifting of the magnet down along a vertical steel wall (considering typical friction coefficient). This parameter is a function of the separation distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 7x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.30 kg / 0.65 lbs 297.0 g / 2.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.20 kg / 0.44 lbs 198.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.22 lbs 99.0 g / 1.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.50 kg / 1.09 lbs 495.0 g / 4.9 N

When mounting a magnet on a vertical surface (e.g., a fridge), it you can count on just approx. 1/5 of its maximum pull force. Gravity and a low friction coefficient influence the fact that holders slide down faster than they detach. Planning a vertical fastening? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a significantly smaller cargo. Application of an anti-slip layer can significantly raise the stability.

2 mm	50%	0.50 kg / 1.09 lbs 495.0 g / 4.9 N

12 mm	100%	0.99 kg / 2.18 lbs 990.0 g / 9.7 N

A thin metal plate is unable to absorb the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a too thin substrate, the field will pass right through and the attraction force will be weaker. To utilize 100% of this neodymium's potential, you need a suitably thick backing of metal. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the product holds weaker. We suggest choosing the steel dimension according to the table below.

Table 5: Working in heat (material behavior) - power drop
MW 7x2 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.99 kg / 2.18 lbs 990.0 g / 9.7 N	OK
40 °C	-2.2%	0.97 kg / 2.13 lbs 968.2 g / 9.5 N	OK
60 °C	-4.4%	0.95 kg / 2.09 lbs 946.4 g / 9.3 N
80 °C	-6.6%	0.92 kg / 2.04 lbs 924.7 g / 9.1 N
100 °C	-28.8%	0.70 kg / 1.55 lbs 704.9 g / 6.9 N

Standard neodymium magnets change their properties power past the thermal threshold. Watch out for overheating – heat can permanently destroy this product. With every degree above norm, the neodymium's force briefly lowers. Refrain from using this magnet close to heaters higher than its working range. Too high temperature will result in irreversible degradation of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Designing a strong closure? Utilize two neodymiums instead of one magnet and a steel. Be careful that when bringing together two magnets, the pinch force is huge. The levitation is marginally weaker than the attraction, but still large.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Calculations show friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Hazards (implants) - warnings
MW 7x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	3.5 cm
Hearing aid	10 Gs (1.0 mT)	2.5 cm

Powerful magnet radiation poses a real danger to electronics and medical implants. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation acts through matter and housings. Special caution must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - warning

Magnetic elements are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when working with powerful specimens.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Note: On a vertical wall, the magnet retains merely a fraction of its max power.

2. Steel saturation

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

3. Thermal stability

*For standard magnets, 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) = 0.39

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 offered product is an exceptionally strong cylindrical magnet, manufactured from durable NdFeB material, which, with dimensions of Ø7x2 mm, guarantees maximum efficiency. The MW 7x2 / N38 component boasts a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.99 kg), this product is in stock from our warehouse in Poland, ensuring quick 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.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 9.76 N with a weight of only 0.58 g, this cylindrical magnet is indispensable in electronics 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 immediate cracking of this professional component. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating 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 the strongest magnets in the same volume (Ø7x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 7 mm and height 2 mm. The value of 9.76 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.58 g. The product has a [NiCuNi] coating, which secures it 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 7 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 through the diameter if your project requires it.

Strengths and weaknesses of rare earth magnets.

Pros

Apart from their strong holding force, neodymium magnets have these key benefits:

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by magnetic disturbances,
A magnet with a smooth nickel surface has better aesthetics,
The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Considering the potential of flexible forming and adaptation to individualized solutions, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
Huge importance in electronics industry – they are commonly used in magnetic memories, electric drive systems, medical equipment, and other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

What to avoid - cons of neodymium magnets: tips and applications.

At strong impacts they can crack, therefore we recommend placing them in special holders. 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
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to complicate diagnosis medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

Breakaway force was determined for ideal contact conditions, including:

on a plate made of structural steel, optimally conducting the magnetic flux
possessing a thickness of minimum 10 mm to ensure full flux closure
with an polished touching surface
under conditions of gap-free contact (surface-to-surface)
under axial application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Effective lifting capacity impacted by specific conditions, such as (from most important):

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Thermal environment – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets

Magnets are brittle

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Crushing risk

Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Do not overheat magnets

Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Flammability

Dust created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Compass and GPS

A powerful magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.

Health Danger

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

Adults only

Always store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.

Sensitization to coating

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.

Data carriers

Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Powerful field

Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
