Pros as well as cons of neodymium magnets.
Advantages
- They do not lose power, even during around ten years – the decrease in power is only ~1% (according to tests),
- They do not lose their magnetic properties even under external field action,
- A magnet with a metallic silver surface looks better,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
- Thanks to the option of accurate molding and customization to individualized projects, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which expands the range of possible applications,
- Wide application in electronics industry – they serve a role in hard drives, motor assemblies, medical equipment, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their power 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 durability 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, in case of application outdoors
- Due to limitations in creating threads and complex shapes in magnets, we propose using a housing - magnetic mount.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these products can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of structural steel, effectively closing the magnetic field
- whose transverse dimension equals approx. 10 mm
- with an polished touching surface
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Distance (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Safe operation
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Bone fractures
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Fire warning
Dust produced during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Danger to pacemakers
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Danger to the youngest
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of kids and pets.
Thermal limits
Do not overheat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Allergic reactions
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands and choose versions in plastic housing.
Keep away from electronics
An intense magnetic field interferes with the operation of magnetometers in phones and navigation systems. Maintain magnets near a device to prevent breaking the sensors.
Eye protection
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Protect data
Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
