Advantages and disadvantages of neodymium magnets.
Benefits
- They do not lose strength, even over around 10 years – the reduction in lifting capacity is only ~1% (theoretically),
- Magnets very well protect themselves against demagnetization caused by external fields,
- In other words, due to the smooth finish of nickel, the element looks attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the potential of precise forming and customization to unique needs, magnetic components can be created in a wide range of forms and dimensions, which makes them more universal,
- Versatile presence in high-tech industry – they are utilized in data components, electric motors, diagnostic systems, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices
Limitations
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- on a base made of mild steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- without the slightest air gap between the magnet and steel
- under axial force vector (90-degree angle)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Pinching danger
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
This is not a toy
These products are not suitable for play. Eating a few magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
Permanent damage
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
ICD Warning
Patients with a ICD must keep an absolute distance from magnets. The magnetism can stop the functioning of the implant.
Magnets are brittle
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets will cause them cracking into shards.
Threat to electronics
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Handling rules
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Dust explosion hazard
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Skin irritation risks
A percentage of the population experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to dermatitis. We recommend wear protective gloves.
Keep away from electronics
A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
