Strengths and weaknesses of rare earth magnets.
Strengths
- They have constant strength, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
- They maintain their magnetic properties even under external field action,
- A magnet with a metallic gold surface has better aesthetics,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- In view of the potential of precise forming and adaptation to individualized requirements, NdFeB magnets can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Versatile presence in modern technologies – they are utilized in mass storage devices, electromotive mechanisms, precision medical tools, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these magnets 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 lifting capacity of the magnet – what affects it?
- on a block made of structural steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface free of scratches
- without the slightest air gap between the magnet and steel
- under vertical force vector (90-degree angle)
- in stable room temperature
Magnet lifting force in use – key factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
H&S for magnets
Magnetic media
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Physical harm
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Demagnetization risk
Control the heat. Exposing the magnet to high heat will ruin its properties and strength.
Risk of cracking
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Immense force
Use magnets with awareness. Their powerful strength can shock even professionals. Stay alert and do not underestimate their force.
Life threat
Individuals with a ICD have to keep an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Warning for allergy sufferers
It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for versions in plastic housing.
Danger to the youngest
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Keep out of reach of kids and pets.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Threat to navigation
A powerful magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a device to prevent breaking the sensors.
