Pros as well as cons of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They retain their magnetic properties even under external field action,
- By using a smooth layer of gold, the element presents an aesthetic look,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to the possibility of accurate forming and customization to individualized projects, neodymium magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
- Fundamental importance in modern technologies – they are utilized in HDD drives, motor assemblies, precision medical tools, also other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
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.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of structural steel, effectively closing the magnetic flux
- with a cross-section of at least 10 mm
- with a plane perfectly flat
- without any clearance between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Protective goggles
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Health Danger
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Finger safety
Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
No play value
Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
Power loss in heat
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Dust is flammable
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Threat to navigation
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop handling magnets and use protective gear.
Immense force
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can move away.
Data carriers
Avoid bringing magnets near a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
