Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They have stable power, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- In other words, due to the metallic layer of nickel, the element gains visual value,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of accurate machining and modifying to atypical applications,
- Key role in innovative solutions – they are used in mass storage devices, electric motors, precision medical tools, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in miniature devices
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in realizing threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Highest magnetic holding force – what affects it?
- using a plate made of mild steel, acting as a magnetic yoke
- with a thickness of at least 10 mm
- with a surface perfectly flat
- with direct contact (no coatings)
- during pulling in a direction vertical to the plane
- at ambient temperature room level
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of any layer (paint, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Electronic devices
Avoid bringing magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Conscious usage
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Danger to the youngest
Product intended for adults. Small elements can be swallowed, leading to severe trauma. Store away from kids and pets.
Dust explosion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
GPS and phone interference
GPS units and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness happens, cease working with magnets and use protective gear.
ICD Warning
For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Demagnetization risk
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Finger safety
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Eye protection
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
