Grip strength decreases drastically per each millimeter of distance. Note that even the smallest gap (e.g., contamination, paint, dust) noticeably diminishes the holding power. Neodymiums operate most effectively at the point of direct contact; air break drastically cuts the force. See how flashily the parameters plummet, when the magnet does not touch flatly to the metal substrate. When designing the arrangement, eliminate redundant distances.

This section shows the approximate holding capacity required to initiate the downward movement of the magnet downwards against a upright metal surface (assuming typical friction). The holding force is relative to the air gap between the magnet and the metal.

When mounting a holder on a vertical plane (e.g., a fridge), it will maintain barely about 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip cause that magnets slide down faster than they detach. Designing a hanger? Remember that the shear force is much weaker than the maximum static pull force. On a smooth steel, the holder will slide down under a significantly smaller weight. Utilizing a rubberized pad can drastically increase the grip.

A thin sheet cannot conduct the full magnetic flux, which wastes potential of the magnet. Should you attach a powerful product to a thin surface, the field will pass right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension according to the table below.

Ordinary NdFeB products lose power above the temperature limit. Avoid high temperatures – high temperature can permanently damage this magnet. With increasing heat, the neodymium's power momentarily drops. Do not use this product close to heaters higher than its operating temperature limit. Too high temperature will cause permanent loss of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) 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 strong neodymiums interact from a much further distance than a magnet and steel combination. The setup of magnet-to-magnet produces a massive flux and a larger range of operation. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the pinch force is extreme. The repulsion force is marginally weaker than the attraction, but still significant.
*Field value in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Results refer to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to IT equipment and pacemakers. These magnets generate a field that disrupts operation of digital equipment. Notice: the unseen radiation acts through matter and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when working with large magnets.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.21

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.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 50x20x5 mm and a weight of 37.5 g, guarantees premium class connection. As a block magnet with high power (approx. 12.69 kg), this product is available off-the-shelf 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. To separate the MPL 50x20x5 / 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.

Plate magnets MPL 50x20x5 / N38 are the foundation for many industrial devices, such as filters catching filings 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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 50x20x5 / N38 model is magnetized through the thickness (dimension 5 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 (50x20 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: 50 mm (length), 20 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 12.69 kg (force ~124.48 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of rare earth magnets.

Benefits

Apart from their superior power, neodymium magnets have these key benefits:

They have constant strength, and over more than ten years their performance decreases symbolically – ~1% (in testing),
Magnets perfectly protect themselves against loss of magnetization caused by external fields,
A magnet with a smooth nickel surface has an effective appearance,
They show high magnetic induction at the operating surface, which increases their power,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
In view of the possibility of accurate shaping and customization to unique needs, NdFeB magnets can be created in a wide range of forms and dimensions, which amplifies use scope,
Wide application in innovative solutions – they are commonly used in mass storage devices, electromotive mechanisms, medical devices, also other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions

Limitations

Disadvantages of NdFeB magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets experience 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
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing threads and complicated forms in magnets, we propose using casing - magnetic holder.
Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

The specified lifting capacity refers to the maximum value, obtained under laboratory conditions, meaning:

on a base made of structural steel, perfectly concentrating the magnetic field
with a cross-section of at least 10 mm
with a plane perfectly flat
without any air gap between the magnet and steel
during pulling in a direction perpendicular to the plane
at standard ambient temperature

Impact of factors on magnetic holding capacity in practice

In real-world applications, the real power depends on many variables, listed from the most important:

Gap (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or debris).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.

H&S for magnets

Powerful field

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

Magnetic interference

A powerful magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.

Risk of cracking

Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Serious injuries

Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.

Demagnetization risk

Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Allergic reactions

Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose encased magnets.

Flammability

Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

ICD Warning
