1. Wall mount (shear)
*Warning: On a vertical surface, the magnet holds merely ~20% of its max power.
2. Plate thickness effect
*Thin metal sheet (e.g. 0.5mm PC case) severely limits the holding force.
3. Thermal stability
*For N38 grade, the safety limit is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.27
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.

Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even during approximately ten years – the decrease in power is only ~1% (based on measurements),
- Neodymium magnets are extremely resistant to demagnetization caused by external field sources,
- Thanks to the elegant finish, the plating of nickel, gold, or silver gives an clean appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Thanks to modularity in forming and the ability to adapt to client solutions,
- Universal use in electronics industry – they are commonly used in mass storage devices, electric motors, advanced medical instruments, as well as multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by even structure
- with zero gap (without coatings)
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
- Plate material – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Adults only
These products are not toys. Swallowing several magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.
Threat to navigation
An intense magnetic field disrupts the operation of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Fire warning
Powder produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Caution required
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Skin irritation risks
Studies show that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, refrain from direct skin contact or opt for coated magnets.
Crushing force
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Health Danger
For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
Electronic hazard
Do not bring magnets near a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Demagnetization risk
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Shattering risk
NdFeB magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them shattering into shards.
