Advantages as well as disadvantages of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- They retain their magnetic properties even under external field action,
- In other words, due to the glossy finish of gold, the element gains visual value,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- 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...
- Due to the possibility of free molding and customization to custom solutions, NdFeB magnets can be created in a broad palette of geometric configurations, which makes them more universal,
- Fundamental importance in advanced technology sectors – they are commonly used in data components, motor assemblies, advanced medical instruments, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 stable to moisture, when using outdoors
- Due to limitations in producing threads and complex forms in magnets, we propose using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum holding power of the magnet – what affects it?
- on a block made of mild steel, perfectly concentrating the magnetic field
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Distance (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be lost into the air.
- Chemical composition of the base – mild steel attracts best. Higher carbon content lower magnetic properties and holding force.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Implant safety
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Hand protection
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Electronic hazard
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Beware of splinters
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Danger to the youngest
Always store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are life-threatening.
Respect the power
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often faster than you can react.
Skin irritation risks
A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in a rash. We recommend wear protective gloves.
Compass and GPS
Remember: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and GPS.
Permanent damage
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Fire warning
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
