Strengths and weaknesses of neodymium magnets.
Advantages
- They do not lose magnetism, even over nearly 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
- They are resistant to demagnetization induced by external magnetic fields,
- A magnet with a shiny nickel surface has better aesthetics,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in constructing and the capacity to modify to individual projects,
- Universal use in advanced technology sectors – they are commonly used in data components, brushless drives, advanced medical instruments, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- with direct contact (no impurities)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the power to be escaped into the air.
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Warnings
Skin irritation risks
It is widely known that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, prevent direct skin contact or select versions in plastic housing.
Compass and GPS
An intense magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to avoid breaking the sensors.
Machining danger
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Immense force
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Eye protection
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Threat to electronics
Do not bring magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Choking Hazard
Always store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
Life threat
Individuals with a ICD have to keep an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
Do not overheat magnets
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
Bone fractures
Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
