Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetism drop when exposed to external magnetic sources,
- A magnet with a smooth nickel surface has an effective appearance,
- Neodymium magnets generate maximum magnetic induction on a small surface, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Possibility of exact machining and modifying to specific conditions,
- Significant place in modern technologies – they are commonly used in magnetic memories, drive modules, medical devices, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Key elements affecting lifting force
- Gap (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Safety rules for work with neodymium magnets
Handling guide
Be careful. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
Machining danger
Dust generated during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Skin irritation risks
Some people suffer from a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in a rash. We strongly advise use safety gloves.
Threat to navigation
An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.
ICD Warning
Individuals with a heart stimulator should maintain an large gap from magnets. The magnetism can stop the functioning of the implant.
Serious injuries
Danger of trauma: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
Operating temperature
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Magnets are brittle
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.
Magnetic media
Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Swallowing risk
Only for adults. Small elements can be swallowed, leading to severe trauma. Store away from kids and pets.
