Magnetic force drops sharply with every subsequent millimeter of gap. Remember that even a very thin break (e.g., dirt, varnish, rust) significantly reduces the pull force. Magnetic products work optimally at the point of direct contact; air break kills the power. See how rapidly the pull force plummet, when the magnet does not touch directly to the metal substrate. When calculating the arrangement, eliminate unnecessary gaps.

This section defines the approximate weight limit necessary to start the downward movement of the magnet downwards on a vertical metal surface (considering standard friction). This value is a function of the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull

When placing a holder on a vertical plane (e.g., a board), it will only hold only approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip mean that magnets move down faster than they detach. Planning a vertical fastening? Note that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will slide down under a much lighter load. Utilizing a rubberized pad can drastically raise the stability.

A thin metal plate is not enough to take in the full magnetic flux, which wastes potential of the magnet. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you require a sufficiently solid backing of metal. The saturation phenomenon means that on thin elements (e.g., thin profiles), the magnet works worse. We suggest choosing the steel dimension from these parameters.

Classic neodymiums lose parameters past the thermal threshold. Watch out for overheating – excessive heat can permanently damage this product. With increasing heat, the magnet's force momentarily lowers. Do not use this product close to heaters exceeding its working range. Ignoring the limit will result in irreversible degradation of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is massive. The repulsion force is marginally weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Results refer to shear force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to IT equipment as well as medical implants. These neodymiums produce a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when playing with powerful specimens.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds only ~20% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) drastically limits the holding force.

3. Power loss vs temp

*For N38 material, 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) = 0.40

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 extremely strong plate magnet made of NdFeB material, which, with dimensions of 3x3x1 mm and a weight of 0.07 g, guarantees the highest quality connection. This magnetic block with a force of 2.29 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 0.23 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (3x3 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 3x3x1 mm, which, at a weight of 0.07 g, makes it an element with high energy density. It is a magnetic block with dimensions 3x3x1 mm and a self-weight of 0.07 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They have stable power, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
Neodymium magnets remain highly resistant to loss of magnetic properties caused by magnetic disturbances,
A magnet with a metallic gold surface has an effective appearance,
Magnetic induction on the working layer of the magnet turns out to be maximum,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of exact modeling and adjusting to atypical conditions,
Huge importance in modern technologies – they are utilized in mass storage devices, electric drive systems, diagnostic systems, and modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited ability of producing nuts in the magnet and complex forms - recommended is casing - magnet mounting.
Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

Breakaway force was determined for optimal configuration, including:

using a plate made of low-carbon steel, serving as a ideal flux conductor
whose thickness equals approx. 10 mm
with an polished touching surface
under conditions of no distance (surface-to-surface)
under vertical force vector (90-degree angle)
in neutral thermal conditions

Lifting capacity in real conditions – factors

It is worth knowing that the magnet holding may be lower depending on elements below, starting with the most relevant:

Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Material type – the best choice is high-permeability steel. Stainless steels may attract less.
Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate decreases the holding force.

Precautions when working with neodymium magnets

Threat to electronics

Do not bring magnets close to a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Machining danger

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Heat warning

Keep cool. Neodymium magnets are susceptible to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Protective goggles

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets leads to them cracking into shards.

Warning for allergy sufferers

Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact and choose versions in plastic housing.

Do not underestimate power

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Warning for heart patients

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

Keep away from children

Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from children and animals.

Physical harm

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

Magnetic interference

Navigation devices and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
