Pros and cons of neodymium magnets.
Benefits
- They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- They maintain their magnetic properties even under strong external field,
- A magnet with a shiny nickel surface has an effective appearance,
- Magnets possess impressive magnetic induction on the outer side,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Thanks to the option of flexible shaping and customization to custom needs, NdFeB magnets can be produced in a wide range of shapes and sizes, which increases their versatility,
- Significant place in future technologies – they serve a role in mass storage devices, electromotive mechanisms, medical equipment, and technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their force 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complex shapes - preferred is a housing - mounting mechanism.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- with a cross-section no less than 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- in stable room temperature
Practical lifting capacity: influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate causes magnetic saturation, causing part of the power to be lost into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Health Danger
Patients with a pacemaker have to keep an safe separation from magnets. The magnetism can stop the operation of the life-saving device.
Threat to electronics
Do not bring magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
Handling guide
Use magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and respect their power.
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Dust explosion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Threat to navigation
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, tablet, and GPS.
Bone fractures
Large magnets can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Product not for children
Only for adults. Small elements pose a choking risk, leading to serious injuries. Keep away from kids and pets.
