Pros as well as cons of Nd2Fe14B magnets.
Strengths
- Their strength remains stable, and after approximately 10 years it decreases only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- In other words, due to the glossy surface of silver, the element is aesthetically pleasing,
- Magnets exhibit exceptionally strong magnetic induction on the surface,
- 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 exact shaping and modifying to complex applications,
- Wide application in future technologies – they serve a role in HDD drives, drive modules, medical equipment, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making threads in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Steel thickness – too thin plate causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of neodymium magnets
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Adults only
NdFeB magnets are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Threat to navigation
A powerful magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets leads to them cracking into shards.
Allergic reactions
Certain individuals suffer from a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. We suggest wear safety gloves.
Bodily injuries
Risk of injury: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Life threat
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Electronic devices
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Handling rules
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Fire risk
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
