Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for almost 10 years – the loss is just ~1% (based on simulations),
- They are resistant to demagnetization induced by external magnetic fields,
- In other words, due to the glossy layer of silver, the element gains a professional look,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in constructing and the capacity to adapt to specific needs,
- Huge importance in future technologies – they are utilized in mass storage devices, electric motors, medical devices, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets lose power 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 when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complex shapes - recommended is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- with an ground touching surface
- without the slightest air gap between the magnet and steel
- under axial force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin plate does not close the flux, causing part of the flux to be wasted to the other side.
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
Magnetic interference
A strong magnetic field interferes with the functioning of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to avoid breaking the sensors.
Combustion hazard
Machining of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Bone fractures
Big blocks can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Conscious usage
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease working with magnets and wear gloves.
Warning for heart patients
Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Safe distance
Equipment safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Danger to the youngest
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are life-threatening.
Shattering risk
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
