Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain attractive force for nearly ten years – the loss is just ~1% (in theory),
- They maintain their magnetic properties even under external field action,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in shaping and the ability to customize to complex applications,
- Universal use in innovative solutions – they are commonly used in HDD drives, motor assemblies, precision medical tools, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power 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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend cover - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- with an ideally smooth contact surface
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Safe operation
Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
Nickel allergy
A percentage of the population have a sensitization to Ni, which is the common plating for NdFeB magnets. Extended handling may cause skin redness. We recommend wear protective gloves.
Eye protection
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
GPS Danger
GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Power loss in heat
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Life threat
People with a pacemaker should maintain an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Product not for children
These products are not suitable for play. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Crushing force
Large magnets can break fingers in a fraction of a second. Do not place your hand between two strong magnets.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Threat to electronics
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
