Advantages and disadvantages of neodymium magnets.
Pros
- Their strength is durable, and after approximately ten years it decreases only by ~1% (theoretically),
- They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
- In other words, due to the reflective layer of nickel, the element gains visual value,
- They show high magnetic induction at the operating surface, which affects their 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...
- Possibility of detailed machining as well as modifying to atypical conditions,
- Wide application in innovative solutions – they find application in HDD drives, electromotive mechanisms, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in miniature devices
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.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of producing threads in the magnet and complex shapes - preferred is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- with a cross-section no less than 10 mm
- with an ground contact surface
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Nickel allergy
Medical facts indicate that nickel (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact or select versions in plastic housing.
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Respect the power
Handle magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.
Keep away from electronics
Be aware: rare earth magnets generate a field that disrupts precision electronics. Maintain a separation from your phone, device, and navigation systems.
Serious injuries
Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Permanent damage
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Cards and drives
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Machining danger
Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep out of reach of kids and pets.
Pacemakers
Patients with a heart stimulator should keep an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
