Strengths and weaknesses of neodymium magnets.
Benefits
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under external field action,
- Thanks to the shiny finish, the plating of nickel, gold-plated, or silver gives an elegant appearance,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which increases force concentration,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of individual forming as well as adapting to complex requirements,
- Key role in modern technologies – they are used in data components, electric motors, diagnostic systems, as well as technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their power 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. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- with a cross-section minimum 10 mm
- with an polished contact surface
- with zero gap (without paint)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (rust, tape, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and lifting capacity.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Do not underestimate power
Handle magnets with awareness. Their immense force can shock even professionals. Be vigilant and respect their power.
Bodily injuries
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Safe distance
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Danger to the youngest
Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are tragic.
Pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Dust is flammable
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Beware of splinters
Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
Compass and GPS
GPS units and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Power loss in heat
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.
