Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have constant strength, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetism drop as a result of external fields,
- Thanks to the smooth finish, the plating of nickel, gold-plated, or silver-plated gives an professional appearance,
- Magnetic induction on the surface of the magnet turns out to be extremely intense,
- 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...
- In view of the option of accurate molding and customization to individualized solutions, NdFeB magnets can be produced in a broad palette of geometric configurations, which increases their versatility,
- Huge importance in modern industrial fields – they are used in hard drives, electromotive mechanisms, medical devices, as well as other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing nuts in the magnet and complicated forms - recommended is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an polished touching surface
- with direct contact (no paint)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Threat to electronics
Do not bring magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Do not drill into magnets
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Pinching danger
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Danger to the youngest
Strictly keep magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are life-threatening.
Implant safety
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Immense force
Be careful. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can react.
Threat to navigation
An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Thermal limits
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Sensitization to coating
Studies show that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact and select versions in plastic housing.
Shattering risk
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
