Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even after nearly ten years – the drop in power is only ~1% (theoretically),
- Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by external interference,
- By using a reflective layer of gold, the element has an aesthetic look,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in designing and the capacity to modify to individual projects,
- Key role in electronics industry – they find application in HDD drives, electric motors, diagnostic systems, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We suggest a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an polished contact surface
- with zero gap (without impurities)
- under perpendicular application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Gap between surfaces – every 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 – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be wasted to the other side.
- Material type – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Risk of cracking
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
Life threat
Patients with a heart stimulator should keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Safe distance
Equipment safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Pinching danger
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Heat warning
Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
GPS and phone interference
GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Skin irritation risks
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop working with magnets and wear gloves.
No play value
Strictly store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are very dangerous.
Flammability
Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Powerful field
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
