Strengths as well as weaknesses of rare earth magnets.
Advantages
- Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (according to research),
- They do not lose their magnetic properties even under close interference source,
- Thanks to the elegant finish, the layer of nickel, gold, or silver gives an clean appearance,
- Magnets are characterized by maximum magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in designing and the capacity to modify to individual projects,
- Significant place in electronics industry – they find application in magnetic memories, drive modules, medical devices, as well as technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of making threads in the magnet and complicated forms - preferred is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, tiny parts of these products can 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
Highest magnetic holding force – what affects it?
- using a base made of low-carbon steel, serving as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with a surface cleaned and smooth
- with total lack of distance (without impurities)
- during detachment in a direction vertical to the mounting surface
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin steel does not close the flux, causing part of the power to be lost to the other side.
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
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. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safe handling of NdFeB magnets
Magnetic interference
Remember: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
No play value
NdFeB magnets are not toys. Eating several magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Maximum temperature
Avoid heat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Fragile material
Neodymium magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them cracking into shards.
Machining danger
Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Immense force
Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
ICD Warning
Individuals with a pacemaker have to keep an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.
Cards and drives
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Pinching danger
Risk of injury: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Nickel coating and allergies
Studies show that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, avoid direct skin contact or opt for encased magnets.
