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.

 warning
Magnetic force drops drastically with every subsequent millimeter of distance. Note that even the smallest gap (e.g., contamination, paint, rust) noticeably diminishes the holding power. Neodymiums operate optimally at the point of direct contact; gap drastically cuts the force. See how rapidly the load capacity fall, when the magnet does not touch tightly to the metal substrate. When planning the assembly, eliminate additional spacers.

The following data calculates the approximate holding capacity required to cause the shifting of the magnet vertically against a upright steel plate (assuming standard friction coefficient). This parameter is a function of the distance between the magnet and the surface.

When hanging a element on a upright surface (e.g., a board), it you can count on barely about 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that products slide down faster than they pop off the substrate. Planning a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller weight. Utilizing a rubberized layer can significantly improve the result.

A thin metal plate is unable to take in the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's potential, you require a sufficiently solid backing of steel. The material oversaturation means that on thin elements (e.g., appliance housings), the holder works worse. We suggest choosing the steel cross-section based on the following data.

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 strong neodymiums attract each other from a wider radius than a magnet and sheet combination. Such a system of two magnets generates a stronger field and a larger range of performance. Designing a strong closure? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the collision energy is massive. The repulsion force is slightly lower than the attraction, but still impressive.
*Field value for N-N configuration reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Calculations apply to friction force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

NdFeB products are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or injury to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when playing 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 wall, the magnet holds merely a fraction of its perpendicular strength.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly limits 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) = 0.35

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.

9.93 zł brutto / pcs
Model MPL 100x50x20 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 1211.32 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. To separate the MPL 100x50x20 / 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. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 123.52 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.
For mounting flat magnets MPL 100x50x20 / N38, it is best to use two-component adhesives (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 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. 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: 100 mm (length), 50 mm (width), and 20 mm (thickness). It is a magnetic block with dimensions 100x50x20 mm and a self-weight of 750 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose power, even after around ten years – the decrease in power is only ~1% (based on measurements),
  • They feature excellent resistance to magnetism drop due to opposing magnetic fields,
  • In other words, due to the glossy layer of silver, the element becomes visually attractive,
  • Magnets are characterized by maximum magnetic induction on the outer side,
  • Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
  • In view of the ability of flexible shaping and customization to custom projects, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
  • Key role in future technologies – they serve a role in mass storage devices, drive modules, medical devices, also modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in compact constructions

Disadvantages

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Limited possibility of creating nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
  • Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products can be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Detachment force of the magnet in optimal conditions – what contributes to it?

The force parameter is a theoretical maximum value conducted under standard conditions:
  • using a sheet made of mild steel, acting as a ideal flux conductor
  • whose thickness equals approx. 10 mm
  • with an polished contact surface
  • with direct contact (no paint)
  • under perpendicular application of breakaway force (90-degree angle)
  • in stable room temperature

Key elements affecting lifting force

Holding efficiency impacted by working environment parameters, mainly (from most important):
  • Distance (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Plate thickness – too thin plate causes magnetic saturation, causing part of the flux to be wasted to the other side.
  • Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
  • Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
  • Operating temperature – neodymium magnets 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 carried out on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets
This is not a toy

Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are very dangerous.

Beware of splinters

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets will cause them breaking into shards.

GPS Danger

A powerful magnetic field interferes with the operation of magnetometers in phones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.

Health Danger

For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Dust explosion hazard

Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

Safe distance

Very strong magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

Nickel coating and allergies

Certain individuals have a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in dermatitis. We strongly advise wear protective gloves.

Finger safety

Risk of injury: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Immense force

Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their force.

Do not overheat magnets

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.
