1. Shear force

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

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely limits the holding force.

3. Thermal stability

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.49

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 13x10x5 / N35H features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 4.03 kg), this product is available off-the-shelf from our warehouse in Poland. 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 13x10x5 / N35H 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. 4.03 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.
For mounting flat magnets MPL 13x10x5 / N35H, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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 13x10x5 / N35H model is magnetized axially (dimension 5 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. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 13x10x5 mm, which, at a weight of 4.88 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 4.03 kg (force ~39.54 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of Nd2Fe14B magnets.

Benefits

Apart from their strong power, neodymium magnets have these key benefits:
  • They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
  • Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
  • A magnet with a metallic silver surface has better aesthetics,
  • Magnetic induction on the working part of the magnet remains very high,
  • 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 forming as well as adapting to complex needs,
  • Universal use in modern industrial fields – they are commonly used in computer drives, motor assemblies, precision medical tools, as well as multitasking production systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of NdFeB magnets:
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power 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
  • 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
  • We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
  • Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum holding power of the magnet – what it depends on?

Information about lifting capacity was determined for the most favorable conditions, taking into account:
  • with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
  • possessing a thickness of minimum 10 mm to ensure full flux closure
  • with a plane free of scratches
  • without the slightest clearance between the magnet and steel
  • under perpendicular application of breakaway force (90-degree angle)
  • at conditions approx. 20°C

Determinants of lifting force in real conditions

Please note that the working load may be lower depending on elements below, in order of importance:
  • Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
  • Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
  • Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
  • 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 was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safe handling of neodymium magnets
Nickel allergy

Studies show that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands or select encased magnets.

Pinching danger

Danger of trauma: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.

Magnetic interference

Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Material brittleness

Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Medical implants

Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Protect data

Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.

Handling guide

Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can move away.

No play value

Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from kids and pets.

Machining danger

Machining of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Thermal limits

Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and strength.
