Other offers
Pros as well as cons of neodymium magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They have excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- A magnet with a shiny silver surface looks better,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of precise modeling as well as adapting to complex conditions,
- Huge importance in modern technologies – they serve a role in computer drives, brushless drives, medical equipment, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of low-carbon steel, acting as a magnetic yoke
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- with total lack of distance (without paint)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Steel thickness – too thin plate does not accept the full field, causing part of the power to be lost into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Sensitization to coating
Some people experience a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause dermatitis. It is best to wear safety gloves.
Compass and GPS
A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.
Beware of splinters
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets leads to them breaking into shards.
Cards and drives
Equipment safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Respect the power
Handle magnets consciously. Their huge power can shock even professionals. Be vigilant and do not underestimate their force.
Maximum temperature
Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Combustion hazard
Dust created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Keep away from children
Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of kids and pets.
Bone fractures
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Danger to pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
