Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for nearly 10 years – the drop is just ~1% (in theory),
- Neodymium magnets remain highly resistant to loss of magnetic properties caused by magnetic disturbances,
- In other words, due to the aesthetic layer of silver, the element looks attractive,
- Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in forming and the ability to adapt to client solutions,
- Huge importance in high-tech industry – they are commonly used in data components, drive modules, precision medical tools, as well as complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these devices can complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- on a plate made of structural steel, effectively closing the magnetic flux
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by even structure
- with direct contact (no impurities)
- under axial force direction (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Air gap (betwixt the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Sensitization to coating
It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands or opt for coated magnets.
Powerful field
Be careful. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can react.
Flammability
Powder produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Magnet fragility
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Life threat
Patients with a pacemaker should maintain an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
Bodily injuries
Big blocks can break fingers instantly. Never place your hand between two strong magnets.
Choking Hazard
Strictly keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.
Operating temperature
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.
Safe distance
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Phone sensors
A powerful magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets close to a device to prevent breaking the sensors.
