Advantages as well as disadvantages of neodymium magnets.
Benefits
- Their power is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- Magnets effectively resist against demagnetization caused by foreign field sources,
- A magnet with a smooth nickel surface is more attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- In view of the possibility of free molding and adaptation to unique needs, neodymium magnets can be created in a variety of geometric configurations, which increases their versatility,
- Universal use in future technologies – they serve a role in data components, electromotive mechanisms, precision medical tools, as well as complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these devices can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- using a base made of mild steel, functioning as a circuit closing element
- whose thickness reaches at least 10 mm
- with a surface perfectly flat
- without any clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safe handling of neodymium magnets
Magnetic media
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Mechanical processing
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Permanent damage
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Powerful field
Exercise caution. Rare earth magnets act from a distance and connect with massive power, often quicker than you can move away.
Bodily injuries
Large magnets can smash fingers instantly. Do not put your hand betwixt two attracting surfaces.
Protective goggles
Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.
Danger to pacemakers
People with a heart stimulator should keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the implant.
Magnetic interference
A strong magnetic field negatively affects the operation of compasses in phones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
Warning for allergy sufferers
Certain individuals have a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Frequent touching might lead to dermatitis. We strongly advise wear safety gloves.
Keep away from children
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
