Advantages as well as disadvantages of neodymium magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Considering the possibility of free molding and adaptation to custom solutions, neodymium magnets can be produced in a broad palette of forms and dimensions, which makes them more universal,
- Significant place in advanced technology sectors – they serve a role in computer drives, electric motors, medical devices, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in producing nuts and complex forms in magnets, we propose using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- on a plate made of mild steel, optimally conducting the magnetic field
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Clearance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be wasted into the air.
- Material type – the best choice is high-permeability steel. Cast iron may attract less.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Keep away from computers
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Magnet fragility
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
ICD Warning
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Handling rules
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Allergic reactions
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Thermal limits
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Bodily injuries
Risk of injury: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Phone sensors
Be aware: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.
Keep away from children
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep out of reach of kids and pets.
Dust explosion hazard
Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
