Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external field influence,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets have exceptionally strong magnetic induction on the working surface,
- 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...
- Considering the option of flexible forming and customization to custom needs, magnetic components can be manufactured in a variety of geometric configurations, which expands the range of possible applications,
- Huge importance in advanced technology sectors – they are used in HDD drives, brushless drives, advanced medical instruments, as well as multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in creating threads and complicated forms in magnets, we recommend using cover - magnetic mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements 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
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a sheet made of high-permeability steel, serving as a circuit closing element
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- with total lack of distance (without paint)
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
Determinants of lifting force in real conditions
- Clearance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – 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.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Keep away from computers
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Magnets are brittle
Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Operating temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Compass and GPS
A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Crushing risk
Danger of trauma: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Medical interference
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Product not for children
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets may result in them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease handling magnets and use protective gear.
Do not underestimate power
Exercise caution. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can react.
