Strengths as well as weaknesses of rare earth magnets.
Pros
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under close interference source,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Possibility of exact shaping and modifying to specific requirements,
- Universal use in modern industrial fields – they find application in HDD drives, electric drive systems, medical equipment, as well as technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of making nuts in the magnet and complex shapes - preferred is casing - mounting mechanism.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane cleaned and smooth
- with total lack of distance (without impurities)
- during pulling in a direction vertical to the plane
- in stable room temperature
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
Safe handling of neodymium magnets
GPS and phone interference
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
ICD Warning
People with a pacemaker must maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Permanent damage
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease handling magnets and use protective gear.
Dust explosion hazard
Powder created during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Product not for children
NdFeB magnets are not intended for children. Eating multiple magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Bone fractures
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Magnetic media
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Caution required
Exercise caution. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can react.
Risk of cracking
Neodymium magnets are ceramic materials, meaning they are very brittle. Collision of two magnets will cause them shattering into shards.
