Pros as well as cons of neodymium magnets.
Benefits
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets prove to be highly resistant to loss of magnetic properties caused by external interference,
- In other words, due to the smooth finish of gold, the element becomes visually attractive,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to freedom in designing and the ability to modify to individual projects,
- Versatile presence in advanced technology sectors – they serve a role in computer drives, electric motors, advanced medical instruments, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these products can be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of mild steel, functioning as a ideal flux conductor
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- with direct contact (no paint)
- under axial force direction (90-degree angle)
- at temperature room level
Impact of factors on magnetic holding capacity in practice
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Steel thickness – too thin steel causes magnetic saturation, causing part of the power to be escaped into the air.
- Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Handling rules
Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and do not underestimate their power.
Risk of cracking
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Danger to pacemakers
Individuals with a ICD should maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Do not drill into magnets
Dust created during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Keep away from children
Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them attracting across intestines, which poses a severe health hazard and requires immediate surgery.
Heat warning
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Cards and drives
Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Warning for allergy sufferers
It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact or select encased magnets.
GPS and phone interference
Navigation devices and smartphones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Finger safety
Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
