Advantages and disadvantages of neodymium magnets.
Strengths
- They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
- Magnets perfectly defend themselves against loss of magnetization caused by external fields,
- A magnet with a shiny silver surface has an effective appearance,
- Magnets are distinguished by exceptionally strong magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the option of accurate forming and customization to specialized needs, magnetic components can be created in a broad palette of forms and dimensions, which amplifies use scope,
- Key role in electronics industry – they are commonly used in mass storage devices, drive modules, medical devices, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complex forms - preferred is a housing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to ensure full flux closure
- with a plane free of scratches
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.
Bodily injuries
Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Heat warning
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its properties and strength.
Nickel coating and allergies
Certain individuals have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to an allergic reaction. We recommend wear safety gloves.
Swallowing risk
Neodymium magnets are not toys. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.
Keep away from electronics
Note: neodymium magnets generate a field that disrupts precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them breaking into shards.
Magnetic media
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Pacemakers
Individuals with a pacemaker have to maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.
Fire warning
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Powerful field
Handle with care. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
