Pros as well as cons of Nd2Fe14B magnets.
Advantages
- Their strength remains stable, and after around 10 years it decreases only by ~1% (according to research),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic layer of nickel, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the potential of accurate forming and customization to custom projects, NdFeB magnets can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Universal use in modern technologies – they serve a role in computer drives, electric motors, medical equipment, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Magnet lifting force in use – key factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Do not give to children
NdFeB magnets are not suitable for play. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.
Fire risk
Dust generated during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Material brittleness
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Sensitization to coating
A percentage of the population experience a contact allergy to nickel, which is the common plating for NdFeB magnets. Frequent touching might lead to an allergic reaction. We recommend wear safety gloves.
ICD Warning
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Protect data
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Caution required
Use magnets consciously. Their huge power can surprise even professionals. Plan your moves and do not underestimate their power.
Bodily injuries
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Precision electronics
Remember: rare earth magnets produce a field that confuses precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
