Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even after around ten years – the decrease in power is only ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external disturbances,
- Thanks to the shimmering finish, the coating of nickel, gold-plated, or silver-plated gives an modern appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of custom shaping as well as modifying to atypical conditions,
- Versatile presence in modern technologies – they serve a role in hard drives, electromotive mechanisms, medical equipment, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose strength 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 very resistant to heat
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complicated forms - recommended is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- with direct contact (without impurities)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Key elements affecting lifting force
- Distance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Protective goggles
NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them shattering into shards.
Product not for children
NdFeB magnets are not intended for children. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Thermal limits
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Allergic reactions
It is widely known that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands and select versions in plastic housing.
Mechanical processing
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Conscious usage
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.
Life threat
For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Magnetic media
Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Finger safety
Danger of trauma: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Compass and GPS
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
