Advantages as well as disadvantages of neodymium magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
- Thanks to the elegant finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to the potential of flexible shaping and customization to unique needs, NdFeB magnets can be modeled in a variety of forms and dimensions, which amplifies use scope,
- Fundamental importance in modern technologies – they are used in hard drives, motor assemblies, advanced medical instruments, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited possibility of creating nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic flux
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- with total lack of distance (without paint)
- under axial force vector (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate reduces the lifting capacity.
Warnings
Bone fractures
Big blocks can crush fingers instantly. Do not place your hand between two strong magnets.
Keep away from computers
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Thermal limits
Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and strength.
Swallowing risk
NdFeB magnets are not intended for children. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires urgent medical intervention.
Safe operation
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Threat to navigation
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Pacemakers
People with a ICD must keep an absolute distance from magnets. The magnetism can interfere with the operation of the life-saving device.
Allergic reactions
Some people experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling might lead to a rash. We suggest use safety gloves.
Fire risk
Powder created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Protective goggles
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
