Pros as well as cons of Nd2Fe14B magnets.
Benefits
- Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They show high resistance to demagnetization induced by external field influence,
- Thanks to the metallic finish, the layer of nickel, gold, or silver gives an aesthetic appearance,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to the ability of precise molding and adaptation to unique requirements, magnetic components can be created in a wide range of geometric configurations, which makes them more universal,
- Universal use in electronics industry – they serve a role in HDD drives, electric drive systems, medical equipment, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in miniature devices
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making threads in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic field
- whose thickness equals approx. 10 mm
- characterized by smoothness
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Keep away from children
Strictly store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are very dangerous.
Heat sensitivity
Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
Machining danger
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Electronic devices
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Bodily injuries
Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Magnets are brittle
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Caution required
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Danger to pacemakers
Individuals with a pacemaker have to keep an absolute distance from magnets. The magnetism can disrupt the functioning of the life-saving device.
Phone sensors
A powerful magnetic field interferes with the operation of compasses in smartphones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
