Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for nearly 10 years – the drop is just ~1% (in theory),
- They have excellent resistance to magnetism drop as a result of external fields,
- A magnet with a metallic silver surface is more attractive,
- Magnetic induction on the surface of the magnet is strong,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of accurate shaping and adaptation to custom requirements, NdFeB magnets can be modeled in a wide range of shapes and sizes, which makes them more universal,
- Huge importance in modern industrial fields – they are used in mass storage devices, brushless drives, precision medical tools, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- Susceptibility to cracking 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 raises their durability
- 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these devices can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- using a base made of mild steel, serving as a magnetic yoke
- possessing a massiveness of min. 10 mm to avoid saturation
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel type – mild steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Flammability
Dust produced during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Danger to the youngest
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
Phone sensors
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.
Allergy Warning
Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, avoid direct skin contact or choose coated magnets.
Thermal limits
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Bodily injuries
Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Safe distance
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
ICD Warning
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Safe operation
Handle magnets with awareness. Their huge power can shock even professionals. Be vigilant and do not underestimate their power.
