Advantages as well as disadvantages of rare earth magnets.
Strengths
- Their power is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- Magnets very well resist against demagnetization caused by foreign field sources,
- Thanks to the smooth finish, the surface of nickel, gold-plated, or silver gives an elegant appearance,
- They are known for high magnetic induction at the operating surface, which increases their power,
- 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...
- Thanks to the potential of free shaping and adaptation to unique requirements, neodymium magnets can be manufactured in a broad palette of shapes and sizes, which increases their versatility,
- Key role in modern technologies – they find application in HDD drives, electromotive mechanisms, medical devices, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what affects it?
- on a plate made of mild steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by smoothness
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Safe operation
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Thermal limits
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and pulling force.
No play value
Product intended for adults. Small elements can be swallowed, causing serious injuries. Keep away from children and animals.
Eye protection
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Bodily injuries
Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Combustion hazard
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Safe distance
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Skin irritation risks
Certain individuals experience a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Frequent touching may cause skin redness. We recommend use protective gloves.
Life threat
Patients with a pacemaker have to keep an large gap from magnets. The magnetic field can stop the operation of the implant.
Precision electronics
A powerful magnetic field disrupts the operation of magnetometers in phones and navigation systems. Do not bring magnets close to a device to prevent breaking the sensors.
