Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (according to research),
- They possess excellent resistance to magnetism drop due to opposing magnetic fields,
- A magnet with a metallic gold surface looks better,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- 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 custom creating as well as adapting to complex needs,
- Fundamental importance in future technologies – they find application in computer drives, drive modules, advanced medical instruments, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their power 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic field
- whose thickness equals approx. 10 mm
- characterized by smoothness
- with direct contact (no paint)
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature room level
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate causes magnetic saturation, causing part of the flux to be escaped into the air.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Heat sensitivity
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Medical implants
Patients with a heart stimulator must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Mechanical processing
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
GPS Danger
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Safe operation
Exercise caution. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can react.
Magnets are brittle
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them breaking into shards.
Do not give to children
Always keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.
Cards and drives
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Allergy Warning
Certain individuals experience a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Prolonged contact can result in dermatitis. We recommend wear protective gloves.
Crushing force
Pinching hazard: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
