Advantages and disadvantages of neodymium magnets.
Strengths
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- They have excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- In other words, due to the aesthetic surface of nickel, the element is aesthetically pleasing,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the ability of precise molding and adaptation to individualized needs, NdFeB magnets can be manufactured in a broad palette of geometric configurations, which increases their versatility,
- Fundamental importance in modern industrial fields – they are used in computer drives, brushless drives, diagnostic systems, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems
Cons
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products can be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with direct contact (no paint)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Key elements affecting lifting force
- Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Machining danger
Dust generated during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Metal Allergy
Certain individuals suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Extended handling can result in dermatitis. It is best to wear protective gloves.
Safe operation
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Magnetic media
Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Physical harm
Risk of injury: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Swallowing risk
Absolutely store magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are life-threatening.
Heat warning
Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Eye protection
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Compass and GPS
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
Warning for heart patients
Patients with a ICD must keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
