Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They possess excellent resistance to magnetism drop as a result of external magnetic sources,
- Thanks to the shiny finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Considering the ability of free molding and customization to custom needs, NdFeB magnets can be modeled in a wide range of forms and dimensions, which increases their versatility,
- Wide application in high-tech industry – they are used in magnetic memories, drive modules, diagnostic systems, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small components of these devices are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- characterized by smoothness
- with total lack of distance (no coatings)
- under vertical application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the plate), as even a very small distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Protect data
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Safe operation
Use magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their power.
Swallowing risk
These products are not suitable for play. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Do not drill into magnets
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Serious injuries
Big blocks can crush fingers instantly. Never put your hand between two strong magnets.
Nickel coating and allergies
A percentage of the population have a contact allergy to Ni, which is the common plating for neodymium magnets. Extended handling might lead to skin redness. We strongly advise wear safety gloves.
Eye protection
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Health Danger
Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Threat to navigation
A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
Operating temperature
Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
