Advantages and disadvantages of rare earth magnets.
Benefits
- Their strength remains stable, and after around 10 years it decreases only by ~1% (theoretically),
- Magnets very well defend themselves against demagnetization caused by external fields,
- In other words, due to the glossy finish of gold, the element becomes visually attractive,
- 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 shape) at temperatures up to 230°C and above...
- Possibility of individual shaping and optimizing to atypical conditions,
- Fundamental importance in electronics industry – they serve a role in hard drives, electromotive mechanisms, advanced medical instruments, as well as multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense 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 lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in creating threads inside the magnet and complex forms.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a plate made of mild steel, effectively closing the magnetic flux
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- without the slightest air gap between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Metal 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 weaken the interaction with the magnet.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Fragile material
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets leads to them shattering into shards.
Implant safety
Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Handling guide
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Data carriers
Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Do not give to children
Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.
Nickel coating and allergies
Certain individuals experience a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause dermatitis. We suggest use protective gloves.
Demagnetization risk
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Fire warning
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
GPS and phone interference
Remember: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Crushing force
Danger of trauma: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.
