Strengths and weaknesses of neodymium magnets.
Advantages
- Their power is durable, and after around 10 years it decreases only by ~1% (theoretically),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- In other words, due to the shiny finish of gold, the element becomes visually attractive,
- They show high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of individual forming and adjusting to specific conditions,
- Universal use in high-tech industry – they serve a role in mass storage devices, electric motors, precision medical tools, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in small systems
Cons
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complex forms in magnets, we recommend using a housing - magnetic mount.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these products are able to be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose thickness is min. 10 mm
- characterized by smoothness
- without any clearance between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance – the presence of any layer (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- 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).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Demagnetization risk
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Skin irritation risks
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for encased magnets.
No play value
NdFeB magnets are not toys. Eating a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.
Keep away from electronics
A strong magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.
Finger safety
Pinching hazard: The pulling power is so great that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Electronic devices
Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Medical interference
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Powerful field
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Material brittleness
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Fire warning
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
