Advantages as well as disadvantages of rare earth magnets.
Strengths
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the metallic finish, the plating of nickel, gold-plated, or silver gives an visually attractive appearance,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- In view of the potential of precise shaping and adaptation to unique projects, NdFeB magnets can be modeled in a variety of forms and dimensions, which increases their versatility,
- Key role in modern technologies – they find application in data components, drive modules, medical equipment, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as 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 force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing threads and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these magnets are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- with direct contact (without paint)
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.
Safe handling of neodymium magnets
Health Danger
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Crushing risk
Large magnets can crush fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.
Demagnetization risk
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Do not give to children
Absolutely keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are very dangerous.
GPS Danger
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
Caution required
Handle magnets with awareness. Their immense force can shock even professionals. Stay alert and respect their power.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop working with magnets and wear gloves.
Protect data
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
