Pros and cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets are characterized by highly resistant to demagnetization caused by external interference,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the working layer of the magnet remains maximum,
- 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 versatility in designing and the ability to customize to unusual requirements,
- Fundamental importance in innovative solutions – they are utilized in magnetic memories, electric motors, precision medical tools, also industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are prone to damage 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 improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of mild steel, serving as a ideal flux conductor
- with a thickness no less than 10 mm
- characterized by even structure
- under conditions of gap-free contact (metal-to-metal)
- under vertical force direction (90-degree angle)
- at room temperature
Lifting capacity in practice – influencing factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Warnings
Machining danger
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Danger to pacemakers
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Sensitization to coating
It is widely known that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or choose coated magnets.
Electronic hazard
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Compass and GPS
Note: neodymium magnets produce a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
Crushing risk
Big blocks can crush fingers instantly. Never place your hand betwixt two strong magnets.
Product not for children
Strictly keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are fatal.
Eye protection
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Caution required
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Operating temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
