Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They do not lose power, even after approximately ten years – the reduction in lifting capacity is only ~1% (based on measurements),
- They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to the possibility of accurate molding and adaptation to custom needs, magnetic components can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in modern industrial fields – they are commonly used in mass storage devices, brushless drives, advanced medical instruments, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in creating threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- using a plate made of low-carbon steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
- Smoothness – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Crushing force
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Do not give to children
Only for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of children and animals.
Danger to pacemakers
Individuals with a ICD must maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
Mechanical processing
Machining of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Demagnetization risk
Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Handling rules
Use magnets consciously. Their huge power can shock even professionals. Be vigilant and do not underestimate their power.
Impact on smartphones
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, device, and navigation systems.
Eye protection
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them shattering into shards.
Skin irritation risks
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or select versions in plastic housing.
Magnetic media
Do not bring magnets close to a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
