Pros and cons of neodymium magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets remain highly resistant to magnetic field loss caused by magnetic disturbances,
- By applying a smooth coating of nickel, the element gains an aesthetic look,
- Magnets are characterized by exceptionally strong magnetic induction on the outer layer,
- 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...
- Possibility of exact creating as well as adapting to defined conditions,
- Huge importance in advanced technology sectors – they find application in magnetic memories, electric drive systems, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by smoothness
- without any insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – mild steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Temperature – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Keep away from electronics
An intense magnetic field interferes with the operation of compasses in phones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
Sensitization to coating
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.
Hand protection
Big blocks can crush fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Data carriers
Do not bring magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Thermal limits
Avoid heat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Handling rules
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Flammability
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Adults only
Always store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into shards.
ICD Warning
Warning for patients: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.
