Pros as well as cons of Nd2Fe14B magnets.
Pros
- They have constant strength, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the reflective surface of silver, the element is aesthetically pleasing,
- Neodymium magnets generate maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of custom forming as well as adjusting to specific conditions,
- Versatile presence in advanced technology sectors – they are used in mass storage devices, electric drive systems, medical equipment, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in creating nuts and complex shapes in magnets, we propose using casing - magnetic mount.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets can complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of mild steel, effectively closing the magnetic flux
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- at ambient temperature room level
What influences lifting capacity in practice
- Gap (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Pacemakers
People with a pacemaker have to maintain an large gap from magnets. The magnetic field can disrupt the operation of the life-saving device.
Do not give to children
Only for adults. Small elements can be swallowed, leading to serious injuries. Store away from kids and pets.
Avoid contact if allergic
A percentage of the population suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Frequent touching may cause skin redness. It is best to wear safety gloves.
Impact on smartphones
Note: rare earth magnets generate a field that confuses sensitive sensors. Keep a safe distance from your mobile, tablet, and GPS.
Cards and drives
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Do not overheat magnets
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Caution required
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Pinching danger
Watch your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Fire warning
Dust produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Magnets are brittle
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
