Pros and cons of rare earth magnets.
Benefits
- They retain full power for nearly ten years – the loss is just ~1% (according to analyses),
- They are resistant to demagnetization induced by external magnetic fields,
- Thanks to the elegant finish, the layer of nickel, gold-plated, or silver-plated gives an modern appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- In view of the option of precise forming and customization to unique requirements, NdFeB magnets can be created in a variety of forms and dimensions, which amplifies use scope,
- Key role in modern technologies – they serve a role in data components, drive modules, medical equipment, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these products can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a block made of mild steel, effectively closing the magnetic field
- whose transverse dimension equals approx. 10 mm
- with a surface cleaned and smooth
- with direct contact (no coatings)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Distance (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Keep away from computers
Very strong magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Handling rules
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.
Danger to pacemakers
For implant holders: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Product not for children
Always keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.
Heat sensitivity
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Mechanical processing
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Physical harm
Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Risk of cracking
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Phone sensors
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.
