Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for around ten years – the loss is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a metallic nickel surface has better aesthetics,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Due to the ability of accurate shaping and adaptation to specialized needs, magnetic components can be manufactured in a wide range of forms and dimensions, which expands the range of possible applications,
- Significant place in modern technologies – they serve a role in magnetic memories, electric motors, advanced medical instruments, also complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their power 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 durability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- on a base made of structural steel, effectively closing the magnetic field
- with a thickness minimum 10 mm
- with a surface free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- under vertical application of breakaway force (90-degree angle)
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Distance – the presence 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 holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Immense force
Handle magnets consciously. Their powerful strength can shock even professionals. Stay alert and do not underestimate their force.
Magnets are brittle
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Life threat
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Keep away from computers
Equipment safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Magnetic interference
Note: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, device, and GPS.
Bone fractures
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.
No play value
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Fire risk
Dust generated during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Do not overheat magnets
Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
