Magnetic force decreases sharply per each millimeter of gap. Remember that every additional insulation layer (e.g., contamination, paint, veneer) significantly diminishes the holding power. Magnetic products hold strongest during direct contact; distance kills the force. Analyze how rapidly the load capacity drop, when the product does not adhere directly to the steel surface. When planning the assembly, eliminate unnecessary gaps.

This section calculates the estimated holding capacity needed to start the downward movement of the magnet downwards on a upright steel plate (assuming standard friction). This parameter is a function of the air gap between the magnet and the metal.

When mounting a holder on a vertical plane (e.g., a car body), it will maintain just about 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip cause that products slip easier than they pull off. Want to create a wall mount? Consider 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 cargo. Utilizing a rubberized pad can significantly improve the result.

A thin metal plate is unable to absorb the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a too thin substrate, the flux will pass right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you need a suitably thick piece of metal. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the magnet shows lower pull force. We advise picking the steel thickness from these parameters.

Classic neodymiums change their properties power after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently damage this magnet. With increasing heat, the magnet's capacity temporarily decreases. Refrain from using this magnet near heat sources exceeding its working range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures than long magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and steel setup. The setup of magnet-to-magnet generates a stronger field and a larger range of operation. 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 huge. The repulsion force is slightly lower than the connection force, but still significant.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Note: Results demonstrate friction force of two same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a large risk to IT equipment and medical implants. These neodymiums produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and glass. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are delicate – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can cause material chips or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the neodymium. Use safety goggles when playing with powerful specimens.

*Note: On a vertical surface, the magnet holds merely a fraction of its nominal pull.

2. Efficiency vs thickness

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

3. Power loss vs temp

*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) = 0.24

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 ring magnet with a hole MP 16x8/4x3 / N38 is created for permanent mounting, where glue might fail or be insufficient. 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 16x8/4x3 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle 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. 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. 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.

A screw or bolt with a thread diameter smaller than 8/4 mm fits this model. 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. Always check that the screw head is not larger than the outer diameter of the magnet (16 mm), so it doesn't protrude beyond the outline.

It is a magnetic ring with a diameter of 16 mm and thickness 3 mm. The pulling force of this model is an impressive 2.78 kg, which translates to 27.29 N in newtons. The mounting hole diameter is precisely 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.

Pros

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

They retain full power for nearly 10 years – the loss is just ~1% (according to analyses),
They feature excellent resistance to magnetism drop when exposed to opposing magnetic fields,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
They show high magnetic induction at the operating surface, which increases their power,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
In view of the possibility of flexible forming and adaptation to specialized solutions, NdFeB magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
Key role in advanced technology sectors – they are commonly used in HDD drives, brushless drives, advanced medical instruments, as well as industrial machines.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:

At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited ability of making nuts in the magnet and complicated shapes - preferred is cover - magnet mounting.
Potential hazard resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these products can complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what it depends on?

The lifting capacity listed is a theoretical maximum value conducted under standard conditions:

with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
whose transverse dimension reaches at least 10 mm
with a surface cleaned and smooth
without the slightest air gap between the magnet and steel
during detachment in a direction vertical to the mounting surface
in temp. approx. 20°C

Determinants of practical lifting force of a magnet

In real-world applications, the actual lifting capacity results from many variables, presented from most significant:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Metal type – not every steel attracts identically. Alloy additives worsen the attraction effect.
Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
Operating temperature – NdFeB sinters 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 plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with neodymium magnets

Shattering risk

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Permanent damage

Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and strength.

Compass and GPS

A powerful magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to avoid damaging the sensors.

Mechanical processing

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.

Crushing force

Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.

Protect data

Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Respect the power

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

Pacemakers

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

Danger to the youngest

These products are not intended for children. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
