Advantages as well as disadvantages of rare earth magnets.
Benefits
- Their magnetic field is durable, and after around 10 years it drops only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external disturbances,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working part of the magnet turns out to be strong,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of detailed machining and optimizing to individual needs,
- Significant place in future technologies – they find application in mass storage devices, electric drive systems, precision medical tools, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in miniature devices
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their strength 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of high-permeability steel, serving as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Bodily injuries
Pinching hazard: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Magnetic media
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Precision electronics
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.
ICD Warning
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Handling guide
Be careful. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can react.
Magnet fragility
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
No play value
Neodymium magnets are not suitable for play. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Warning for allergy sufferers
Studies show that nickel (standard magnet coating) is a strong allergen. If you have an allergy, refrain from direct skin contact and select encased magnets.
Combustion hazard
Powder produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Maximum temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
