Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- Their magnetic field is durable, and after approximately ten years it drops only by ~1% (according to research),
- Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external magnetic fields,
- In other words, due to the reflective finish of nickel, the element gains a professional look,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- In view of the potential of precise shaping and customization to specialized requirements, neodymium magnets can be modeled in a broad palette of geometric configurations, which expands the range of possible applications,
- Wide application in modern industrial fields – they are utilized in computer drives, drive modules, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating nuts in the magnet and complex shapes - recommended is casing - magnetic holder.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of mild steel, acting as a ideal flux conductor
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
Key elements affecting lifting force
- Distance (between the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
Magnetic interference
An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to avoid damaging the sensors.
Material brittleness
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into small pieces.
Choking Hazard
These products are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
Combustion hazard
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Allergy Warning
Studies show that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or choose versions in plastic housing.
Hand protection
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Respect the power
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Power loss in heat
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Life threat
Patients with a ICD have to keep an absolute distance from magnets. The magnetism can interfere with the functioning of the life-saving device.
Data carriers
Do not bring magnets near a purse, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
