Advantages as well as disadvantages of neodymium magnets.
Advantages
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They show high resistance to demagnetization induced by external magnetic fields,
- Thanks to the metallic finish, the plating of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- 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...
- Thanks to versatility in designing and the ability to adapt to specific needs,
- Versatile presence in high-tech industry – they find application in data components, drive modules, medical devices, as well as other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these products are able to 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
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- characterized by even structure
- with zero gap (no coatings)
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Distance – existence of foreign body (paint, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Material brittleness
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Serious injuries
Large magnets can break fingers instantly. Do not place your hand betwixt two strong magnets.
Impact on smartphones
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Heat sensitivity
Do not overheat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Life threat
People with a ICD must keep an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.
Handling guide
Handle with care. Rare earth magnets act from a distance and connect with huge force, often quicker than you can move away.
Keep away from children
These products are not toys. Swallowing a few magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Electronic devices
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Nickel allergy
Some people experience a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching can result in an allergic reaction. We suggest wear safety gloves.
