Advantages and disadvantages of rare earth magnets.
Strengths
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a shiny silver surface has better aesthetics,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the potential of free shaping and adaptation to custom needs, neodymium magnets can be manufactured in a variety of geometric configurations, which increases their versatility,
- Huge importance in advanced technology sectors – they are used in data components, electromotive mechanisms, medical equipment, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in creating threads and complex shapes in magnets, we propose using cover - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Air gap (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Base smoothness – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Warnings
Allergy Warning
Some people suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Frequent touching may cause a rash. We strongly advise wear protective gloves.
Precision electronics
Note: neodymium magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Bone fractures
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Adults only
Neodymium magnets are not toys. Accidental ingestion of a few magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires immediate surgery.
Heat sensitivity
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and strength.
Flammability
Dust created during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Fragile material
Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them breaking into small pieces.
Safe operation
Exercise caution. Rare earth magnets act from a distance and snap with huge force, often faster than you can move away.
Data carriers
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Medical interference
Individuals with a heart stimulator have to keep an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
