Pros as well as cons of Nd2Fe14B magnets.
Pros
- They do not lose power, even during around ten years – the reduction in power is only ~1% (according to tests),
- They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- In other words, due to the aesthetic layer of gold, the element gains a professional look,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to modularity in constructing and the capacity to adapt to individual projects,
- Versatile presence in advanced technology sectors – they are utilized in magnetic memories, drive modules, medical devices, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves 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 as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated forms in magnets, we propose using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these devices are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- with a thickness of at least 10 mm
- with a surface cleaned and smooth
- with zero gap (no paint)
- during detachment in a direction vertical to the mounting surface
- at temperature room level
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
- Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
Warnings
Dust is flammable
Combustion risk: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Operating temperature
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Medical interference
People with a heart stimulator have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Handling guide
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Electronic hazard
Do not bring magnets near a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Crushing risk
Big blocks can break fingers instantly. Never place your hand between two strong magnets.
Do not give to children
Absolutely store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
Warning for allergy sufferers
A percentage of the population have a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to a rash. We strongly advise use safety gloves.
Beware of splinters
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Keep away from electronics
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
