Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain attractive force for around ten years – the loss is just ~1% (in theory),
- They are resistant to demagnetization induced by external disturbances,
- Thanks to the shimmering finish, the layer of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- Magnetic induction on the top side of the magnet is maximum,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the ability of flexible forming and customization to specialized solutions, magnetic components can be created in a broad palette of forms and dimensions, which expands the range of possible applications,
- Key role in advanced technology sectors – they serve a role in hard drives, drive modules, diagnostic systems, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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 resistant to moisture, when using outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- using a plate made of high-permeability steel, acting as a ideal flux conductor
- with a thickness minimum 10 mm
- characterized by even structure
- with total lack of distance (without coatings)
- under axial force vector (90-degree angle)
- at temperature room level
Key elements affecting lifting force
- Clearance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Flammability
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Keep away from electronics
GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Swallowing risk
Strictly store magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.
Magnetic media
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Allergy Warning
Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact and select versions in plastic housing.
Power loss in heat
Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Pinching danger
Danger of trauma: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Warning for heart patients
People with a heart stimulator have to maintain an safe separation from magnets. The magnetic field can disrupt the operation of the implant.
Risk of cracking
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
