Pros as well as cons of rare earth magnets.
Strengths
- They do not lose magnetism, even during nearly ten years – the drop in strength is only ~1% (according to tests),
- They feature excellent resistance to magnetism drop as a result of opposing magnetic fields,
- Thanks to the metallic finish, the coating of nickel, gold, or silver gives an aesthetic appearance,
- Neodymium magnets generate maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Considering the possibility of accurate molding and customization to unique needs, magnetic components can be created in a wide range of shapes and sizes, which increases their versatility,
- Wide application in high-tech industry – they are utilized in HDD drives, electric motors, medical equipment, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves 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 durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- using a plate made of high-permeability steel, functioning as a ideal flux conductor
- with a thickness of at least 10 mm
- characterized by lack of roughness
- under conditions of no distance (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Metal Allergy
Medical facts indicate that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or opt for versions in plastic housing.
Safe operation
Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and respect their power.
Magnet fragility
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them cracking into small pieces.
Danger to pacemakers
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Pinching danger
Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Dust is flammable
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Precision electronics
Navigation devices and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Electronic hazard
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Maximum temperature
Avoid heat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Keep away from children
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.
