Advantages as well as disadvantages of neodymium magnets.
Pros
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They feature excellent resistance to magnetism drop due to opposing magnetic fields,
- Thanks to the shimmering finish, the layer of nickel, gold, or silver gives an aesthetic appearance,
- Neodymium magnets ensure maximum magnetic induction on a small area, 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 shape) at temperatures up to 230°C and above...
- Considering the possibility of free shaping and adaptation to unique requirements, neodymium magnets can be manufactured in a broad palette of geometric configurations, which expands the range of possible applications,
- Key role in innovative solutions – they are commonly used in HDD drives, drive modules, advanced medical instruments, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic field
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a surface free of scratches
- with total lack of distance (without coatings)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Plate material – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Fire warning
Dust created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Respect the power
Be careful. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.
Electronic devices
Data protection: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Product not for children
Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Keep away from kids and pets.
Shattering risk
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Crushing risk
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
ICD Warning
People with a pacemaker must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
Compass and GPS
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.
Allergic reactions
Certain individuals suffer from a contact allergy to Ni, which is the common plating for neodymium magnets. Prolonged contact can result in an allergic reaction. It is best to use safety gloves.
Maximum temperature
Keep cool. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
