Strengths and weaknesses of neodymium magnets.
Advantages
- They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- In other words, due to the aesthetic layer of nickel, the element becomes visually attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- 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 forming as well as optimizing to complex needs,
- Key role in modern technologies – they are commonly used in mass storage devices, brushless drives, diagnostic systems, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex forms in magnets, we recommend using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at room temperature
Magnet lifting force in use – key factors
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the flux to be escaped to the other side.
- Chemical composition of the base – mild steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Precautions when working with neodymium magnets
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Pacemakers
For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Eye protection
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Choking Hazard
Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop handling magnets and use protective gear.
Physical harm
Risk of injury: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Do not underestimate power
Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can move away.
Compass and GPS
A strong magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.
Cards and drives
Very strong magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
