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 mm of spacing. Remember that even the smallest gap (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnets work most effectively in perfect adhesion; air break nullifies the force. Notice how quickly the parameters drop, when the magnet does not adhere flatly to the metal substrate. When designing the arrangement, avoid unnecessary gaps.

The table below calculates the approximate force needed to start the shifting of the magnet vertically along a vertical steel plate (assuming typical friction coefficient). This parameter is a function of the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 5x5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.23 kg / 0.51 pounds 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 pounds 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 pounds 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 pounds 385.0 g / 3.8 N

When mounting a magnet on a vertical wall (e.g., a fridge), it you can count on barely approx. 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip mean that magnets slide down easier than they pop off the substrate. Planning a vertical fastening? Remember that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will slip down under a significantly smaller load. Utilizing a rubberized pad can significantly improve the result.

12 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N

A too thin steel is unable to focus the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To achieve 100% of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the product holds weaker. We advise picking the steel cross-section according to the table below.

Table 5: Thermal resistance (stability) - power drop

40 °C	-2.2%	0.75 kg / 1.66 pounds 753.1 g / 7.4 N	OK
60 °C	-4.4%	0.74 kg / 1.62 pounds 736.1 g / 7.2 N

100 °C	-28.8%	0.55 kg / 1.21 pounds 548.2 g / 5.4 N

Standard neodymium magnets irreversibly lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this magnet. With increasing heat, the neodymium's capacity temporarily lowers. Avoid using this magnet close to heaters higher than its safe range. Exceeding the critical threshold will cause permanent loss of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than long magnets. Red status in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet combination. Such a system of two magnets produces a massive flux and a wider radius of operation. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the collision energy is massive. The repulsion force is slightly lower than the connection force, but still large.
*Flux density between like poles is approximately ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Note: Calculations apply to shear force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to electronics as well as pacemakers. These NdFeB products generate a flux that disrupts operation of digital equipment. Remember: the unseen radiation acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when working with large magnets.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Note: On a vertical surface, the magnet holds merely approx. 20-30% of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) drastically weakens the holding force.

3. Heat tolerance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.46

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.

Model MPL 5x5x2 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 7.57 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding 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 0.77 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 5x5x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. 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. 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 5x5x2 / N38 model is magnetized axially (dimension 2 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 (5x5 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 5x5x2 mm, which, at a weight of 0.38 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 5x5x2 mm and a self-weight of 0.38 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:

They do not lose strength, even during approximately 10 years – the drop in power is only ~1% (based on measurements),
Neodymium magnets prove to be exceptionally resistant to loss of magnetic properties caused by external interference,
Thanks to the metallic finish, the plating of nickel, gold, or silver-plated gives an modern appearance,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of precise modeling and modifying to concrete needs,
Versatile presence in modern industrial fields – they are utilized in HDD drives, brushless drives, advanced medical instruments, and modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
Possible danger related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical in case of swallowing.
With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The force parameter is a result of laboratory testing executed under the following configuration:

on a plate made of mild steel, perfectly concentrating the magnetic flux
with a cross-section no less than 10 mm
with an ideally smooth contact surface
with zero gap (without impurities)
for force acting at a right angle (pull-off, not shear)
at ambient temperature room level

Magnet lifting force in use – key factors

Please note that the magnet holding may be lower subject to the following factors, starting with the most relevant:

Distance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
Plate thickness – too thin plate does not accept the full field, causing part of the flux to be escaped to the other side.
Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Handling rules

Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Power loss in heat

Keep cool. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Protect data

Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

This is not a toy

NdFeB magnets are not intended for children. Swallowing several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.

Warning for allergy sufferers

Some people experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to dermatitis. We strongly advise use protective gloves.

Mechanical processing

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Medical interference

Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Precision electronics

Remember: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your phone, device, and GPS.

Material brittleness

Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
