Grip strength decreases drastically with every mm of spacing. Remember that even the smallest gap (e.g., dirt, varnish, rust) strongly reduces the pull force. Magnets hold strongest in perfect adhesion; gap drastically cuts the force. Analyze how flashily the parameters drop, when the product does not touch flatly to the metal substrate. When calculating the arrangement, avoid additional spacers.

This section defines the approximate force required to initiate the slippage of the magnet downwards on a vertical metal surface (assuming typical friction). This value is a function of the distance between the magnet and the metal.

When placing a holder on a vertical wall (e.g., a car body), it you can count on only approx. 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that products move down faster than they pull off. Planning a wall mount? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will give way down under a significantly smaller weight. Using a rubber pad can significantly improve the result.

A thin metal plate is not enough to take in the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you need a suitably thick piece of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet shows lower pull force. We advise picking the steel dimension from these parameters.

Standard neodymium magnets irreversibly lose power past the thermal threshold. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's force temporarily decreases. Avoid using this product close to ovens higher than its operating temperature limit. Exceeding the critical threshold will cause permanent loss of magnetism.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Red status in the table signals 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 connection of magnet-to-magnet produces a massive flux and a larger range of operation. Want to build a strong closure? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is huge. The levitation is slightly lower than the attraction, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Note: Calculations demonstrate shear force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronics and medical implants. These magnets produce a flux that destroys function of sensitive medical devices. Notice: the unseen radiation passes through tissues and housings. Increased vigilance must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a strong collision with metal can result in shattering. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when playing with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Warning: On a vertical surface, the magnet retains merely ~20% of its perpendicular strength.

2. Plate thickness effect

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.38

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.

This product is an incredibly powerful cylinder magnet, manufactured from modern NdFeB material, which, at dimensions of Ø10x30 mm, guarantees optimal power. The MW 10x30 / N38 component features high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 1.92 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 18.79 N with a weight of only 17.67 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using 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 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 (Ø10x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 30 mm. The key parameter here is the holding force amounting to approximately 1.92 kg (force ~18.79 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 10 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 diametrically if your project requires it.

Strengths and weaknesses of rare earth magnets.

Pros

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

They retain full power for almost 10 years – the drop is just ~1% (in theory),
They maintain their magnetic properties even under external field action,
Thanks to the shimmering finish, the layer of nickel, gold, or silver gives an elegant appearance,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Possibility of detailed machining and optimizing to precise needs,
Universal use in innovative solutions – they are utilized in data components, brushless drives, advanced medical instruments, also industrial machines.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these products are able to be problematic in diagnostics medical when they are in the body.
Due to neodymium price, their price is higher than average,

Pull force analysis

Maximum holding power of the magnet – what it depends on?

The force parameter is a theoretical maximum value conducted under specific, ideal conditions:

with the application of a sheet made of special test steel, guaranteeing maximum field concentration
with a cross-section no less than 10 mm
characterized by lack of roughness
without any clearance between the magnet and steel
during pulling in a direction vertical to the plane
at ambient temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

Effective lifting capacity is influenced by specific conditions, such as (from priority):

Clearance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Steel thickness – insufficiently thick plate does not close the flux, causing part of the flux to be lost into the air.
Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets

Fire warning

Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.

Fragile material

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets leads to them breaking into small pieces.

This is not a toy

Adult use only. Small elements pose a choking risk, leading to serious injuries. Store away from kids and pets.

Cards and drives

Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).

Heat sensitivity

Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.

Avoid contact if allergic

Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact or opt for coated magnets.

Threat to navigation

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Implant safety

Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

Respect the power

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Serious injuries

Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
