Pros and cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They retain their magnetic properties even under strong external field,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They feature high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in designing and the ability to modify to client solutions,
- Wide application in future technologies – they are commonly used in magnetic memories, brushless drives, precision medical tools, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complex forms in magnets, we propose using cover - magnetic mount.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products can 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 hinders application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- on a plate made of mild steel, effectively closing the magnetic flux
- with a thickness of at least 10 mm
- with a plane free of scratches
- with total lack of distance (without impurities)
- during pulling in a direction vertical to the plane
- at standard ambient temperature
What influences lifting capacity in practice
- Distance (betwixt the magnet and the metal), as even a very small distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin steel does not close the flux, causing part of the power to be wasted to the other side.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Danger to pacemakers
Patients with a pacemaker should maintain an large gap from magnets. The magnetic field can disrupt the operation of the implant.
Danger to the youngest
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of children and animals.
Respect the power
Exercise caution. Neodymium magnets attract from a long distance and connect with huge force, often faster than you can react.
Fragile material
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Fire risk
Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Magnetic interference
Be aware: rare earth magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, device, and GPS.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness occurs, cease handling magnets and wear gloves.
Thermal limits
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Crushing risk
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Safe distance
Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
