Frequently asked questions

How much will a block magnet really hold?
The catalogue force is measured in full contact with smooth steel at least 10 mm thick, pulled perpendicular, at about 20 °C. On 1 mm sheet about 50% of that value remains, on 0.5 mm about 25%. Mounted on a vertical wall the realistic figure is 20–30%, because the load is then in shear rather than in tension.
What is the maximum working temperature?
Standard N-series grades up to 80 °C, and N50, N52 and N54 up to 60 °C. Above the maximum working temperature the loss stops being reversible. The Curie temperature, at which magnetic properties are lost completely, is about 310 °C.
What safety factor should I allow?
At least twice the mass of the item, and three to five times for vertical mounting. The margin covers sheet thickness, surface condition, any layer of paint or rust, and vibration.

Pulling power weakens drastically with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, paint, rust) significantly reduces the pull force. Neodymiums hold most effectively in perfect adhesion; air break drastically cuts the force. See how quickly the load capacity plummet, when the product does not touch tightly to the steel surface. When calculating the arrangement, discard additional spacers.

The following data calculates the approximate holding capacity necessary to start the downward movement of the magnet down along a vertical metal surface (considering typical friction coefficient). The holding force is relative to the separation distance between the magnet and the surface.

When hanging a holder on a vertical plane (e.g., a board), it you can count on just about 1/5 of nominal attraction strength. Gravitational force as well as a low friction coefficient cause that magnets move down faster than they pull off. Planning a vertical fastening? Note that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the holder will give way down under a much lighter cargo. Application of an anti-slip pad can effectively raise the stability.

A thin sheet is unable to conduct the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To achieve 100% of this magnet's potential, you require a sufficiently solid piece of metal. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel cross-section according to the table below.

Classic neodymiums lose strength after exceeding the maximum temperature. Protect against heat – high temperature can permanently damage this product. As the temperature rises, the magnet's power momentarily lowers. Avoid using this product near heat sources exceeding its working range. Too high temperature will result in destruction of magnetic properties.
*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and sheet setup. The setup of two magnets produces a massive flux and a wider radius of operation. Designing a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still large.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
* Calculations show shear force of two same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field is a large risk to electronics and pacemakers. These NdFeB products generate a field that destroys function of digital equipment. Remember: the unseen radiation penetrates the body and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or injury to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when working with large magnets.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains merely a fraction of its nominal pull.

2. Steel saturation

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

3. Power loss vs temp

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.54

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 Pc (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 Pc 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.

Component MPL 15x2x30 / N38 features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 0.68 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.
Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 0.68 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
They constitute a key element in the production of 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.
For mounting flat magnets MPL 15x2x30 / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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.
Standardly, the MPL 15x2x30 / N38 model is magnetized through the thickness (dimension 30 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (15x2 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 15x2x30 mm, which, at a weight of 6.75 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 0.68 kg (force ~6.68 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of neodymium magnets.

Advantages

Besides their tremendous strength, neodymium magnets offer the following advantages:
  • They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
  • Magnets effectively resist against loss of magnetization caused by external fields,
  • In other words, due to the smooth finish of nickel, the element gains visual value,
  • Magnets exhibit extremely high magnetic induction on the outer side,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of exact shaping as well as optimizing to atypical requirements,
  • Key role in modern technologies – they serve a role in magnetic memories, electric motors, precision medical tools, and complex engineering applications.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
  • We recommend a housing - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
  • Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

Holding force of 0.68 kg is a measurement result conducted under the following configuration:
  • with the application of a sheet made of special test steel, ensuring maximum field concentration
  • whose thickness reaches at least 10 mm
  • with a surface perfectly flat
  • without the slightest clearance between the magnet and steel
  • during detachment in a direction perpendicular to the mounting surface
  • at room temperature

Determinants of lifting force in real conditions

Holding efficiency is affected by working environment parameters, such as (from priority):
  • Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
  • Plate thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped to the other side.
  • Steel type – low-carbon steel gives the best results. Alloy admixtures reduce magnetic permeability and holding force.
  • Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.

Warnings
Handling rules

Use magnets consciously. Their huge power can surprise even experienced users. Plan your moves and respect their force.

Compass and GPS

Note: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.

Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Beware of splinters

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.

Operating temperature

Do not overheat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Threat to electronics

Data protection: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

No play value

Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from children and animals.

Health Danger

People with a heart stimulator must keep an absolute distance from magnets. The magnetic field can stop the functioning of the implant.

Skin irritation risks

It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose versions in plastic housing.

Crushing risk

Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
