Advantages as well as disadvantages of neodymium magnets.
Benefits
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets prove to be remarkably resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a smooth nickel surface is more attractive,
- Magnetic induction on the surface of the magnet is strong,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the ability of precise molding and adaptation to custom needs, magnetic components can be created in a broad palette of geometric configurations, which makes them more universal,
- Universal use in innovative solutions – they are used in magnetic memories, electric drive systems, precision medical tools, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- with an ideally smooth touching surface
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
- Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the holding force.
H&S for magnets
Medical implants
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Crushing force
Large magnets can break fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Machining danger
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Protect data
Equipment safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Phone sensors
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Handling guide
Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can move away.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease handling magnets and wear gloves.
Eye protection
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Power loss in heat
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Keep away from children
Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
