Physical analysis of the magnet - data

The following information are the outcome of a mathematical analysis. Values were calculated on algorithms for the class Nd₂Fe₁₄B. Real-world parameters might slightly deviate from the simulation results. Treat these calculations as a preliminary roadmap when designing systems.

Grip strength decreases significantly per each millimeter of spacing. Remember that even a very thin break (e.g., contamination, varnish, dust) strongly weakens the grip. Neodymiums work strongest in perfect adhesion; air break drastically cuts the power. Observe how flashily the load capacity plummet, when the product does not touch flatly to the metal substrate. When planning the arrangement, avoid redundant distances.

This section calculates the estimated weight limit needed to cause the sliding of the magnet vertically along a upright steel plate (considering standard friction). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MP 14x8/4x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.76 kg / 1.67 pounds 759.0 g / 7.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.51 kg / 1.12 pounds 506.0 g / 5.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.25 kg / 0.56 pounds 253.0 g / 2.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.27 kg / 2.79 pounds 1265.0 g / 12.4 N

When placing a magnet on a upright wall (e.g., a board), it will only hold only about 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient cause that products slide down faster than they pop off the substrate. Designing a wall mount? Note that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a much lighter cargo. Utilizing a rubberized pad can effectively increase the grip.

A thin sheet is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid element of metal. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel thickness based on the following data.

Classic neodymiums change their properties parameters past the thermal threshold. Protect against heat – high temperature can irreversibly damage this product. As the temperature rises, the neodymium's force briefly drops. Refrain from using this product in hot environments higher than its working range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization under lower heat stress than taller cylinders. The danger warning in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the collision energy is massive. The repulsion force is marginally weaker than the attraction, but still large.
*The magnetic induction between like poles drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Figures show shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to IT equipment as well as medical implants. These NdFeB products produce a flux that disrupts operation of sensitive medical devices. Remember: the unseen radiation penetrates the body and glass. Special caution must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning
MP 14x8/4x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.89 km/h (8.02 m/s)	0.10 J
30 mm	49.27 km/h (13.69 m/s)	0.30 J
50 mm	63.61 km/h (17.67 m/s)	0.50 J
100 mm	89.96 km/h (24.99 m/s)	0.99 J

Magnetic elements are very brittle – a collision with steel causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when playing with large magnets.

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. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Caution: On a vertical wall, the magnet retains merely ~20% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely weakens 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) = 0.28

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.

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 14x8/4x3 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a flexible washer 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. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for indoor use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.

The inner hole diameter determines the maximum size of the mounting element. 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 (14 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø14x3 mm and a weight of 3.18 g. The key parameter here is the lifting capacity amounting to approximately 2.53 kg (force ~24.85 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 8/4 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Besides their tremendous strength, neodymium magnets offer the following advantages:

They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
They possess excellent resistance to magnetism drop as a result of external magnetic sources,
In other words, due to the reflective finish of nickel, the element looks attractive,
The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
Possibility of precise forming as well as adjusting to specific needs,
Significant place in innovative solutions – they serve a role in mass storage devices, drive modules, diagnostic systems, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems

Limitations

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in creating threads and complex forms in magnets, we recommend using a housing - magnetic mount.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Highest magnetic holding force – what contributes to it?

The force parameter is a measurement result executed under specific, ideal conditions:

using a sheet made of low-carbon steel, acting as a magnetic yoke
whose thickness reaches at least 10 mm
characterized by even structure
with direct contact (no coatings)
under perpendicular force vector (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Practical lifting capacity: influencing factors

It is worth knowing that the working load may be lower influenced by elements below, starting with the most relevant:

Gap (betwixt the magnet and the plate), because even a very small distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Angle of force application – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

H&S for magnets

Bone fractures

Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Skin irritation risks

Some people have a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Frequent touching might lead to a rash. We recommend wear safety gloves.

This is not a toy

Strictly store magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.

Compass and GPS

Remember: rare earth magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Operating temperature

Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.

Data carriers

Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

Conscious usage

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Beware of splinters

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets leads to them cracking into shards.

Implant safety

Patients with a pacemaker should keep an large gap from magnets. The magnetic field can disrupt the operation of the implant.

Fire risk

Dust generated during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
