Advantages as well as disadvantages of neodymium magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
- Thanks to the smooth finish, the plating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Considering the possibility of accurate forming and adaptation to specialized solutions, NdFeB magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
- Huge importance in advanced technology sectors – they find application in HDD drives, brushless drives, advanced medical instruments, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using casing - magnetic mount.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- using a base made of low-carbon steel, serving as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane free of scratches
- without any clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Distance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Do not overheat magnets
Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Metal Allergy
Studies show that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and opt for versions in plastic housing.
Powerful field
Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can move away.
Threat to electronics
Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
GPS Danger
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Bodily injuries
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Choking Hazard
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Store out of reach of kids and pets.
Dust explosion hazard
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Pacemakers
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Protective goggles
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
