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.

Magnetic force decreases drastically with every subsequent millimeter of distance. Remember that even a very thin break (e.g., dirt, paint, rust) noticeably diminishes the holding power. Magnets hold optimally in perfect adhesion; distance kills the power. Notice how quickly the pull force drop, when the product does not touch directly to the metal substrate. When calculating the arrangement, eliminate additional spacers.

This section presents the estimated force sufficient to cause the slippage of the magnet downwards along a upright metal surface (considering standard friction). The holding force is relative to the air gap between the magnet and the surface.

When placing a magnet on a upright surface (e.g., a car body), it will maintain barely about 1/5 of its nominal power. Gravitational force as well as a weak degree of grip cause that holders move down faster than they pull off. Designing a wall mount? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the element will slip down under a noticeably lighter weight. Utilizing a rubberized coating can significantly increase the grip.

A too thin steel is not enough to take in the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid piece of metal. The saturation effect means that on thin elements (e.g., car bodies), the magnet shows lower pull force. We advise picking the steel thickness from these parameters.

Classic neodymiums change their properties power above the temperature limit. Protect against heat – heat can irreversibly damage this product. As the temperature rises, the neodymium's capacity temporarily decreases. Refrain from using this product near heat sources exceeding its safe range. Too high temperature will lead to permanent loss of magnetism.
*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and sheet setup. Such a system of magnet-to-magnet produces a massive flux and a further horizon of operation. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the pinch force is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*Field value between like poles reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Estimates refer to friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to IT equipment and medical implants. These neodymiums produce a field that destroys function of digital equipment. Notice: the invisible magnetic field penetrates the body and glass. Special caution must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are prone to chipping – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.
The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds only a fraction of its max power.

2. Plate thickness effect

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

3. Temperature resistance

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.13

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 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 30x15x2 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 2.11 kg), this product is available immediately from our warehouse in Poland. Furthermore, 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 2.11 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 30x15x2 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 2.11 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.
Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
Standardly, the MPL 30x15x2 / N38 model is magnetized axially (dimension 2 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 30x15x2 mm, which, at a weight of 6.75 g, makes it an element with high energy density. It is a magnetic block with dimensions 30x15x2 mm and a self-weight of 6.75 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of rare earth magnets.

Pros

Apart from their superior holding force, neodymium magnets have these key benefits:
  • They do not lose strength, even after around 10 years – the decrease in lifting capacity is only ~1% (according to tests),
  • Neodymium magnets are characterized by highly resistant to magnetic field loss caused by magnetic disturbances,
  • Thanks to the smooth finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
  • Magnets have huge magnetic induction on the surface,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Possibility of precise forming as well as adapting to precise conditions,
  • Huge importance in advanced technology sectors – they are used in computer drives, electromotive mechanisms, advanced medical instruments, and modern systems.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their 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
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in producing nuts and complicated forms in magnets, we recommend using casing - magnetic holder.
  • Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
  • With budget limitations the cost of neodymium magnets is a challenge,

Lifting parameters

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

The load parameter shown refers to the limit force, measured under laboratory conditions, specifically:
  • using a base made of high-permeability steel, functioning as a circuit closing element
  • whose thickness equals approx. 10 mm
  • characterized by even structure
  • under conditions of gap-free contact (metal-to-metal)
  • during detachment in a direction perpendicular to the mounting surface
  • at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Please note that the magnet holding will differ subject to elements below, in order of importance:
  • Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
  • Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safe handling of NdFeB magnets
This is not a toy

Strictly keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.

Fire risk

Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Protect data

Do not bring magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.

Warning for allergy sufferers

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.

Do not overheat magnets

Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Medical implants

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Bone fractures

Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!

GPS and phone interference

GPS units and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Protective goggles

Neodymium magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them cracking into small pieces.

Conscious usage

Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
