Advantages as well as disadvantages of rare earth magnets.
Benefits
- Their power remains stable, and after approximately ten years it decreases only by ~1% (according to research),
- They show high resistance to demagnetization induced by external magnetic fields,
- Thanks to the shimmering finish, the surface of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in designing and the ability to adapt to complex applications,
- Key role in electronics industry – they are utilized in data components, electromotive mechanisms, medical devices, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an polished contact surface
- without the slightest air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Clearance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin plate causes magnetic saturation, causing part of the power to be escaped into the air.
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Compass and GPS
A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Respect the power
Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
Finger safety
Large magnets can smash fingers instantly. Do not put your hand between two strong magnets.
Threat to electronics
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Product not for children
Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.
Avoid contact if allergic
Certain individuals experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause a rash. It is best to wear safety gloves.
Fire risk
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Thermal limits
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Magnet fragility
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Medical implants
People with a ICD should maintain an safe separation from magnets. The magnetic field can stop the operation of the implant.
