Pros as well as cons of rare earth magnets.
Pros
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under close interference source,
- A magnet with a smooth gold surface has an effective appearance,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of exact modeling and adapting to specific requirements,
- Key role in electronics industry – they are commonly used in computer drives, electromotive mechanisms, medical devices, also multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets lose their force 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited possibility of creating nuts in the magnet and complex forms - recommended is a housing - mounting mechanism.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- with a surface free of scratches
- without any insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Distance (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Beware of splinters
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
GPS and phone interference
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Danger to the youngest
Strictly keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.
Do not overheat magnets
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Electronic devices
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Conscious usage
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Finger safety
Danger of trauma: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Skin irritation risks
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and select versions in plastic housing.
Implant safety
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Fire risk
Machining of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
