Pros as well as cons of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even after nearly 10 years – the drop in strength is only ~1% (based on measurements),
- They retain their magnetic properties even under external field action,
- In other words, due to the metallic finish of silver, the element gains a professional look,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of individual modeling and adapting to concrete applications,
- Fundamental importance in modern industrial fields – they are used in HDD drives, electric motors, advanced medical instruments, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. 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 recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics 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
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- under axial application of breakaway force (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Clearance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be lost into the air.
- Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
H&S for magnets
Metal Allergy
A percentage of the population suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Frequent touching can result in skin redness. It is best to wear protective gloves.
Impact on smartphones
Remember: rare earth magnets generate a field that interferes with sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Physical harm
Big blocks can smash fingers instantly. Under no circumstances place your hand between two strong magnets.
Fire warning
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Heat sensitivity
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Beware of splinters
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Handling guide
Be careful. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can move away.
Health Danger
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Cards and drives
Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Product not for children
NdFeB magnets are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates urgent medical intervention.
