Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They have constant strength, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are extremely resistant to loss of magnetic properties caused by magnetic disturbances,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets have exceptionally strong magnetic induction on the active area,
- 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 custom forming as well as optimizing to atypical conditions,
- Significant place in innovative solutions – they are used in hard drives, electric drive systems, medical devices, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in small systems
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complicated forms - preferred is cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- with a cross-section minimum 10 mm
- characterized by even structure
- without any air gap between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
What influences lifting capacity in practice
- Clearance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
- Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Medical interference
Individuals with a pacemaker should keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Dust explosion hazard
Dust generated during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Bodily injuries
Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Compass and GPS
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.
Keep away from children
Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.
Cards and drives
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Maximum temperature
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Material brittleness
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Allergy Warning
Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands or choose encased magnets.
Safe operation
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
