Frequently asked questions

What pull rating should I choose for a workshop block magnet?
A catalogue pull rating is measured under stated test conditions. A painted or thin steel surface, a gap or a load acting along the surface can reduce the practical grip. Choose a margin based on the actual installation and read the product card.
Are block neodymium magnets available in more durable versions?
Sintered NdFeB is brittle and can corrode if its coating is damaged. Check the coating and operating-temperature limit of the selected product. A housing may help protect a magnet in an application exposed to impacts.
How should I choose block magnets for mounting a structure?
First check the steel grade and thickness, then any gap created by paint or dirt, and finally the direction of the applied load. Compare these conditions with the specifications of the selected magnet; do not rely on grade alone.

Magnetic force decreases significantly with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., contamination, paint, veneer) significantly weakens the grip. Neodymiums hold optimally at the point of direct contact; gap nullifies the force. Observe how flashily the load capacity drop, when the product does not adhere directly to the metal substrate. When planning the arrangement, eliminate redundant distances.

The following data shows the approximate force necessary to start the downward movement of the magnet down against a upright metal surface (considering standard friction). This value varies with the gap size between the magnet and the metal.

When placing a element on a upright surface (e.g., a fridge), it you can count on just approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip influence the fact that magnets slip easier than they pop off the substrate. Designing a vertical fastening? Consider that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the element will give way down under a much lighter load. Utilizing a rubberized coating can effectively improve the result.

A thin metal plate cannot absorb the full magnetic flux, which weakens actual performance of the magnet. Should you mount a strong magnet to a weak sheet, the flux will pass right through and the holding will be smaller. To squeeze 100% of this magnet's potential, you need a suitably thick element of metal. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the product works worse. We suggest choosing the steel dimension from these parameters.

The table estimates the reversible force change relative to 20°C, assuming a Br coefficient of -0.11%/°C and force proportional to Br². This is a simplified model with unchanged contact and geometry, not a measurement. Above the material limit, neither force nor irreversible magnetization loss is predicted.
The temperature limit comes from this product’s material data. Permissible conditions also depend on geometry and the magnetic circuit. Without B-H curves for the specific grade and temperature, Pc alone does not determine irreversible demagnetization. Values within the material range do not guarantee the allowable temperature of the complete assembly.

Two magnets attract each other from a much further distance than a magnet and steel combination. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is extreme. The levitation is slightly lower than the attraction, but still impressive.
*The magnetic induction between like poles drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Results demonstrate friction force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when handling with powerful specimens.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds only ~20% of its perpendicular strength.

2. Plate thickness effect

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

3. Thermal stability

N38: the maximum material working temperature is 80°C. Permitted conditions also depend on the shape and magnetic circuit.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.27

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 50x30x8 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 224.28 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.
Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 50x30x8 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. 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. Thanks to the flat surface and high force (approx. 22.87 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.
For mounting flat magnets MPL 50x30x8 / N38, it is best to use strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.
Standardly, the MPL 50x30x8 / N38 model is magnetized axially (dimension 8 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.
The presented product is a neodymium magnet with precisely defined parameters: 50 mm (length), 30 mm (width), and 8 mm (thickness). It is a magnetic block with dimensions 50x30x8 mm and a self-weight of 90 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
  • They do not lose their magnetic properties even under close interference source,
  • A magnet with a metallic silver surface is more attractive,
  • Neodymium magnets achieve maximum magnetic induction on a small area, which increases force concentration,
  • 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...
  • Thanks to the possibility of precise forming and adaptation to unique needs, neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies use scope,
  • Universal use in innovative solutions – they serve a role in computer drives, motor assemblies, diagnostic systems, also technologically advanced constructions.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Problematic aspects of neodymium magnets and ways of using them
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complex forms in magnets, we propose using cover - magnetic mount.
  • Health risk resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets can be problematic in diagnostics medical after entering the body.
  • Due to complex production process, their price is higher than average,

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

Breakaway force was determined for optimal configuration, including:
  • with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
  • with a cross-section minimum 10 mm
  • with a plane perfectly flat
  • without any insulating layer between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at standard ambient temperature

Determinants of practical lifting force of a magnet

During everyday use, the real power is determined by a number of factors, ranked from crucial:
  • Distance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
  • Base massiveness – too thin plate does not accept the full field, causing part of the power to be escaped to the other side.
  • Steel grade – the best choice is pure iron steel. Cast iron may attract less.
  • Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
  • Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with NdFeB magnets
Protect data

Device Safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).

GPS Danger

Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.

Crushing force

Big blocks can break fingers in a fraction of a second. Never place your hand between two strong magnets.

Danger to pacemakers

Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Demagnetization risk

Do not exceed the maximum operating temperature stated in the specifications of the particular product. The limit depends on the material, geometry and operating arrangement; there is no single threshold for all neodymium magnets. Overheating can permanently weaken a magnet.

Dust is flammable

Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.

Risk of cracking

Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.

Swallowing risk

Neodymium magnets are not toys. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.

Allergic reactions

Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands or choose versions in plastic housing.

Respect the power

Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.
