Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- Their strength is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the shiny finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- Neodymium magnets create maximum magnetic induction on a small area, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Considering the possibility of free molding and customization to custom projects, NdFeB magnets can be manufactured in a variety of geometric configurations, which increases their versatility,
- Key role in future technologies – they serve a role in computer drives, electric motors, advanced medical instruments, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in small systems
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce 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 - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of making threads in the magnet and complicated forms - preferred is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- possessing a massiveness of min. 10 mm to avoid saturation
- with a plane perfectly flat
- with direct contact (without paint)
- under perpendicular application of breakaway force (90-degree angle)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Precautions when working with neodymium magnets
GPS and phone interference
A powerful magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Keep away from computers
Very strong magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Permanent damage
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Immense force
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Warning for heart patients
Individuals with a pacemaker have to keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Danger to the youngest
NdFeB magnets are not toys. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Crushing force
Pinching hazard: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Dust is flammable
Dust generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Allergy Warning
Some people experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact might lead to skin redness. We strongly advise wear safety gloves.
Magnet fragility
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
