Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They retain attractive force for almost 10 years – the drop is just ~1% (based on simulations),
- Magnets very well protect themselves against demagnetization caused by ambient magnetic noise,
- A magnet with a shiny nickel surface has better aesthetics,
- Magnetic induction on the top side of the magnet remains impressive,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
- Due to the option of free shaping and adaptation to individualized projects, neodymium magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Significant place in high-tech industry – they are utilized in magnetic memories, motor assemblies, precision medical tools, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating threads in the magnet and complex forms - preferred is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- 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 it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- under conditions of no distance (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- in stable room temperature
Key elements affecting lifting force
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin steel does not close the flux, causing part of the power to be wasted into the air.
- Material type – ideal substrate is pure iron steel. Cast iron may attract less.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Do not drill into magnets
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Thermal limits
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Magnet fragility
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Bodily injuries
Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Be careful!
Phone sensors
An intense magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.
Powerful field
Use magnets consciously. Their huge power can shock even professionals. Be vigilant and respect their power.
Keep away from children
Absolutely keep magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.
Cards and drives
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Health Danger
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Allergy Warning
Certain individuals suffer from a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Extended handling might lead to dermatitis. It is best to use protective gloves.
