Strengths as well as weaknesses of neodymium magnets.
Benefits
- They do not lose power, even over approximately 10 years – the reduction in strength is only ~1% (based on measurements),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Thanks to versatility in forming and the capacity to customize to client solutions,
- Universal use in advanced technology sectors – they find application in HDD drives, electromotive mechanisms, advanced medical instruments, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- with zero gap (without coatings)
- during detachment in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be lost into the air.
- Steel type – mild steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Respect the power
Use magnets consciously. Their immense force can shock even experienced users. Stay alert and do not underestimate their power.
Keep away from computers
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Physical harm
Pinching hazard: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Implant safety
Individuals with a ICD have to maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them cracking into small pieces.
Keep away from electronics
Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.
This is not a toy
Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Keep away from children and animals.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Fire warning
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
