Strengths as well as weaknesses of neodymium magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They feature excellent resistance to magnetism drop when exposed to external magnetic sources,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
- 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 precise shaping as well as modifying to individual requirements,
- Significant place in high-tech industry – they are commonly used in computer drives, electric motors, diagnostic systems, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in miniature devices
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of producing threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these products 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
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of mild steel, effectively closing the magnetic field
- whose transverse dimension reaches at least 10 mm
- with an polished touching surface
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Key elements affecting lifting force
- Distance – the presence of any layer (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Pinching danger
Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Beware of splinters
Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Handling rules
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Heat sensitivity
Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and pulling force.
GPS and phone interference
Be aware: neodymium magnets produce a field that confuses precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.
Data carriers
Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Warning for heart patients
For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Skin irritation risks
It is widely known that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or opt for encased magnets.
Mechanical processing
Dust generated during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Product not for children
Only for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of kids and pets.
