Pros and cons of rare earth magnets.
Pros
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets remain highly resistant to demagnetization caused by external field sources,
- In other words, due to the metallic finish of nickel, the element looks attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of custom modeling as well as optimizing to specific requirements,
- Versatile presence in electronics industry – they are commonly used in magnetic memories, electric motors, advanced medical instruments, also technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complicated shapes in magnets, we propose using cover - magnetic mount.
- Health risk 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 tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- whose thickness is min. 10 mm
- with a plane free of scratches
- with direct contact (without paint)
- under vertical force vector (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Air gap (betwixt the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Warnings
Keep away from electronics
GPS units and mobile phones are highly sensitive to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Finger safety
Danger of trauma: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Nickel coating and allergies
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or opt for coated magnets.
Fire risk
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
Choking Hazard
Adult use only. Small elements can be swallowed, leading to serious injuries. Store away from kids and pets.
Handling guide
Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.
Heat warning
Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Warning for heart patients
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Data carriers
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Risk of cracking
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
