Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets remain highly resistant to magnetic field loss caused by external interference,
- In other words, due to the aesthetic layer of gold, the element gains visual value,
- Magnetic induction on the working part of the magnet is maximum,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Due to the ability of precise shaping and customization to unique needs, magnetic components can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Universal use in future technologies – they find application in hard drives, electric motors, medical devices, and complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium 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 extremely resistant to heat
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complicated forms - recommended is a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Highest magnetic holding force – what affects it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Machining danger
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Health Danger
Individuals with a heart stimulator have to keep an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Safe operation
Handle with care. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can move away.
Protect data
Very strong magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
GPS and phone interference
GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
Demagnetization risk
Keep cool. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Allergy Warning
It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, avoid direct skin contact or opt for versions in plastic housing.
Magnet fragility
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep out of reach of kids and pets.
Finger safety
Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
