Grip strength drops drastically per each millimeter of gap. Note that even a microscopic distance (e.g., contamination, paint, dust) significantly reduces the pull force. Neodymiums hold optimally in perfect adhesion; gap drastically cuts the power. Notice how rapidly the load capacity fall, when the product does not touch tightly to the steel surface. When calculating the arrangement, discard additional spacers.

The table below defines the estimated shear load needed to cause the shifting of the magnet downwards along a vertical steel wall (assuming standard friction). The holding force is relative to the distance between the magnet and the metal.

When mounting a holder on a vertical plane (e.g., a car body), it you can count on only about 1/5 of its maximum pull force. Gravitational force and a weak degree of grip cause that holders slip faster than they pop off the substrate. Designing a wall mount? Note that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will give way down under a noticeably lighter weight. Application of an anti-slip layer can significantly increase the grip.

A thin sheet is not enough to focus the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To achieve 100% of this neodymium's power, you need a suitably thick element of metal. The material oversaturation causes that on delicate walls (e.g., car bodies), the product works worse. We suggest choosing the steel dimension based on the following data.

Classic neodymiums lose power above the temperature limit. Avoid high temperatures – high temperature can permanently demagnetize this product. As the temperature rises, the neodymium's capacity briefly lowers. Do not use this magnet near heat sources exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a neodymium and metal combination. The connection of two magnets produces a massive flux and a wider radius of operation. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the impact force is extreme. The repulsion force is slightly lower than the attraction, but still large.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Attention: Results demonstrate shear force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a large risk to electronics and pacemakers. These magnets produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation acts through matter and housings. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or dangerous crushing to skin. 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 ends with a crack of the magnet. Wear eye protection when handling 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!

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet holds merely approx. 20-30% of its max power.

2. Efficiency vs thickness

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Mounting is clean and reversible, unlike gluing. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This is a crucial issue when working with model MP 36.2x11/6x7.5 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force will cause the ring to crack. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but does not ensure full waterproofing. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

A screw or bolt with a thread diameter smaller than 11/6 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Always check that the screw head is not larger than the outer diameter of the magnet (36.2 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø36.2x7.5 mm and a weight of 56.3 g. The key parameter here is the lifting capacity amounting to approximately 17.12 kg (force ~167.95 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 11/6 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. In the case of connecting two rings, make sure one is turned the right way. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

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

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
They retain their magnetic properties even under external field action,
A magnet with a shiny silver surface is more attractive,
Magnets possess maximum magnetic induction on the outer layer,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
In view of the potential of precise molding and adaptation to unique projects, NdFeB magnets can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
Fundamental importance in advanced technology sectors – they serve a role in mass storage devices, electric motors, medical devices, also other advanced devices.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Cons

Problematic aspects of neodymium magnets and ways of using them

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. 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
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, small components of these products are able to be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Detachment force of the magnet in optimal conditions – what contributes to it?

Breakaway force was defined for the most favorable conditions, including:

on a base made of structural steel, optimally conducting the magnetic field
whose thickness reaches at least 10 mm
with a plane free of scratches
without the slightest clearance between the magnet and steel
during detachment in a direction vertical to the plane
in stable room temperature

Practical aspects of lifting capacity – factors

During everyday use, the actual holding force depends on several key aspects, ranked from the most important:

Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Load vector – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Plate material – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets

Serious injuries

Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Use thick gloves.

Allergy Warning

Medical facts indicate that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands and select versions in plastic housing.

Flammability

Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

No play value

Only for adults. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.

Conscious usage

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Danger to pacemakers

People with a ICD should keep an safe separation from magnets. The magnetism can interfere with the functioning of the implant.

Do not overheat magnets

Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.

Safe distance

Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.

GPS Danger

A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.

Shattering risk

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
