Pros as well as cons of neodymium magnets.
Advantages
- They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization induced by external field influence,
- A magnet with a metallic silver surface looks better,
- Magnets have very high magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of exact machining as well as adapting to atypical conditions,
- Versatile presence in electronics industry – they serve a role in magnetic memories, motor assemblies, medical devices, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with a plane free of scratches
- with total lack of distance (no impurities)
- during pulling in a direction vertical to the mounting surface
- in stable room temperature
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic permeability and holding force.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Flammability
Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Pinching danger
Big blocks can break fingers instantly. Do not place your hand betwixt two attracting surfaces.
ICD Warning
Warning for patients: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Precision electronics
A strong magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.
Handling rules
Handle magnets consciously. Their powerful strength can surprise even experienced users. Stay alert and do not underestimate their power.
Beware of splinters
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
Safe distance
Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Do not give to children
Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Store away from kids and pets.
Operating temperature
Do not overheat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
