Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They retain attractive force for almost 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
- By applying a lustrous coating of nickel, the element acquires an elegant look,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- 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 precise forming as well as adapting to individual requirements,
- Versatile presence in modern industrial fields – they serve a role in data components, electric drive systems, medical equipment, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in miniature devices
Cons
- They are fragile upon too strong 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
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a plane perfectly flat
- with zero gap (without impurities)
- during detachment in a direction perpendicular to the mounting surface
- at room temperature
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
Safe handling of neodymium magnets
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from kids and pets.
Finger safety
Risk of injury: The attraction force is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Beware of splinters
Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Allergy Warning
A percentage of the population suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching can result in a rash. It is best to use protective gloves.
Flammability
Machining of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Electronic devices
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Life threat
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Phone sensors
GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Caution required
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
