Pulling power drops significantly with every subsequent millimeter of gap. Note that every additional insulation layer (e.g., dirt, varnish, rust) noticeably diminishes the holding power. Magnetic products operate most effectively in perfect adhesion; air break kills the power. See how quickly the pull force drop, when the product does not adhere flatly to the metal substrate. When planning the mounting, avoid redundant distances.

The following data indicates the estimated weight limit sufficient to start the shifting of the magnet downwards on a vertical steel plate (assuming standard friction). This value varies with the separation distance between the magnet and the metal.

When placing a magnet on a upright plane (e.g., a car body), it will only hold barely about 20%-30% of nominal attraction strength. Gravity and a low friction coefficient influence the fact that magnets move down faster than they pop off the substrate. Want to create a hanger? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a significantly smaller cargo. Application of an anti-slip pad can drastically improve the result.

A too thin steel is not enough to take in the full magnetic flux, which weakens actual performance of the magnet. If you mount a strong magnet to a thin surface, the flux will pass right through and the attraction force will be weaker. To squeeze the maximum of this magnet's power, you need a suitably thick piece of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the product shows lower pull force. We suggest choosing the steel thickness from these parameters.

Classic neodymiums irreversibly lose parameters past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly damage this product. With increasing heat, the neodymium's capacity briefly drops. Do not use this magnet close to heaters exceeding its working range. Too high temperature will result in permanent loss of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a much further distance than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a further horizon of performance. Designing a solid fastener? Apply two magnets instead of one magnet and a steel. Be careful that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
Note: Calculations apply to shear force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronic devices and medical implants. These neodymiums generate a flux that disrupts operation of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Magnetic elements are very brittle – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

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

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 holds merely approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.64

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. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. 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 62x42x25 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force will cause the ring to crack. It's a good idea to use a rubber spacer under the screw head, which will cushion the stresses. 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 is not sufficient for rain. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Aesthetic mounting requires selecting the appropriate head size.

It is a magnetic ring with a diameter of 62 mm and thickness 25 mm. The key parameter here is the lifting capacity amounting to approximately 58.67 kg (force ~575.60 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 42 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths as well as weaknesses of rare earth magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:

They do not lose power, even after nearly ten years – the decrease in lifting capacity is only ~1% (theoretically),
Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external magnetic fields,
By covering with a reflective coating of silver, the element acquires an elegant look,
The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
Possibility of precise forming as well as adapting to complex requirements,
Universal use in advanced technology sectors – they are commonly used in computer drives, motor assemblies, diagnostic systems, and multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Problematic aspects of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Limited ability of making threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
With mass production the cost of neodymium magnets is a challenge,

Lifting parameters

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

Holding force of 58.67 kg is a measurement result executed under specific, ideal conditions:

with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
with a cross-section of at least 10 mm
characterized by even structure
with direct contact (no coatings)
during detachment in a direction vertical to the plane
at room temperature

Determinants of lifting force in real conditions

In practice, the real power is determined by a number of factors, listed from most significant:

Clearance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

H&S for magnets

Conscious usage

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

Pinching danger

Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Threat to navigation

Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.

Electronic devices

Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

Dust explosion hazard

Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Power loss in heat

Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Magnet fragility

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them breaking into small pieces.

Adults only

Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.

Danger to pacemakers

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

Nickel allergy

Some people have a sensitization to nickel, which is the standard coating for neodymium magnets. Prolonged contact may cause a rash. We suggest use protective gloves.

Security! More info about hazards in the article: Magnet Safety Guide.
