Strengths and weaknesses of neodymium magnets.
Strengths
- They retain attractive force for almost ten years – the drop is just ~1% (based on simulations),
- They maintain their magnetic properties even under strong external field,
- A magnet with a shiny silver surface has an effective appearance,
- Neodymium magnets generate maximum magnetic induction on a contact point, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of accurate shaping and adaptation to specialized projects, neodymium magnets can be created in a wide range of shapes and sizes, which amplifies use scope,
- Versatile presence in high-tech industry – they are commonly used in HDD drives, electric drive systems, precision medical tools, also technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- 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 lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using casing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- using a base made of low-carbon steel, serving as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- without any air gap between the magnet and steel
- during detachment in a direction vertical to the plane
- at standard ambient temperature
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 veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Base massiveness – too thin plate does not close the flux, causing part of the power to be wasted to the other side.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Precision electronics
A powerful magnetic field interferes with the operation of compasses in smartphones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and use protective gear.
Caution required
Use magnets with awareness. Their immense force can shock even professionals. Be vigilant and do not underestimate their power.
Keep away from computers
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Crushing risk
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, crushing everything in their path. Be careful!
Health Danger
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Combustion hazard
Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Power loss in heat
Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Protective goggles
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Do not give to children
Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
