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.

Grip strength drops significantly with every subsequent millimeter of spacing. Keep in mind that even the smallest gap (e.g., contamination, varnish, dust) significantly reduces the pull force. Magnetic products work strongest in perfect adhesion; air break drastically cuts the power. Observe how quickly the parameters fall, when the magnet does not touch flatly to the steel surface. When planning the mounting, discard unnecessary gaps.

The following data presents the theoretical force necessary to initiate the downward movement of the magnet down on a vertical metal surface (assuming typical friction). This value is a function of the distance between the magnet and the surface.

When hanging a holder on a vertical wall (e.g., a car body), it you can count on only about 1/5 of nominal attraction strength. Gravity and a low friction coefficient influence the fact that holders move down faster than they pull off. Want to create a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will slip down under a much lighter weight. Application of an anti-slip layer can significantly increase the grip.

A too thin steel is incapable of conduct the entire magnetic field, which squanders power of the holder. If you install a neodymium to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize full efficiency of this neodymium's potential, you require a sufficiently solid backing of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the holder works worse. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products lose parameters above the temperature limit. Protect against heat – high temperature can permanently demagnetize this magnet. With increasing heat, the magnet's force temporarily lowers. Avoid using this magnet close to ovens higher than its operating temperature limit. Ignoring the limit will lead to irreversible degradation of magnetic properties.
*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet generates a stronger field and a larger range of performance. Designing a strong closure? Use a pair of magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the collision energy is huge. The levitation is a bit weaker than the connection force, but still large.
*Field value between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Calculations apply to friction force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a large risk to electronics and pacemakers. These magnets produce a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and glass. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or injury to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when working with large magnets.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains only approx. 20-30% of its max power.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.48

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.

Model MPL 7x7x3 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 15.70 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.
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 7x7x3 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, 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 wind generators and material handling systems. Thanks to the flat surface and high force (approx. 1.60 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
Standardly, the MPL 7x7x3 / N38 model is magnetized through the thickness (dimension 3 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 (7x7 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.
The presented product is a neodymium magnet with precisely defined parameters: 7 mm (length), 7 mm (width), and 3 mm (thickness). It is a magnetic block with dimensions 7x7x3 mm and a self-weight of 1.1 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Strengths

Apart from their consistent power, neodymium magnets have these key benefits:
  • Their strength is durable, and after around ten years it decreases only by ~1% (according to research),
  • They retain their magnetic properties even under strong external field,
  • By applying a decorative layer of gold, the element acquires an professional look,
  • Magnetic induction on the working layer of the magnet turns out to be maximum,
  • 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...
  • Due to the ability of precise molding and customization to custom needs, NdFeB magnets can be manufactured in a variety of forms and dimensions, which increases their versatility,
  • Huge importance in future technologies – they are used in data components, drive modules, medical devices, and other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems

Disadvantages

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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 usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in creating threads and complex shapes in magnets, we propose using cover - magnetic mechanism.
  • Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process medical after entering the body.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Magnetic strength at its maximum – what affects it?

The lifting capacity listed is a measurement result conducted under standard conditions:
  • using a sheet made of mild steel, acting as a ideal flux conductor
  • with a cross-section minimum 10 mm
  • with an polished touching surface
  • without the slightest air gap between the magnet and steel
  • under axial application of breakaway force (90-degree angle)
  • in stable room temperature

Lifting capacity in real conditions – factors

In practice, the actual holding force is determined by a number of factors, presented from most significant:
  • Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
  • Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
  • Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Crushing risk

Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Conscious usage

Be careful. Neodymium magnets act from a distance and connect with massive power, often quicker than you can move away.

Nickel coating and allergies

It is widely known that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and opt for encased magnets.

Keep away from computers

Do not bring magnets near a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.

Danger to pacemakers

People with a ICD have to keep an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.

GPS Danger

A powerful magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.

Do not give to children

Strictly keep magnets away from children. Ingestion danger is high, and the consequences of magnets connecting inside the body are life-threatening.

Combustion hazard

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Risk of cracking

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
