Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- Magnets perfectly defend themselves against loss of magnetization caused by external fields,
- In other words, due to the reflective finish of nickel, the element is aesthetically pleasing,
- Neodymium magnets create maximum magnetic induction on a small surface, 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...
- Possibility of custom modeling as well as adjusting to defined applications,
- Key role in future technologies – they are used in hard drives, electric drive systems, diagnostic systems, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- whose thickness is min. 10 mm
- with an polished contact surface
- with zero gap (no impurities)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Gap (between the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Dust explosion hazard
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and strength.
Keep away from electronics
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Allergic reactions
A percentage of the population have a contact allergy to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause an allergic reaction. We suggest wear protective gloves.
Electronic devices
Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
Serious injuries
Large magnets can smash fingers instantly. Do not put your hand between two strong magnets.
Material brittleness
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
Immense force
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Health Danger
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Swallowing risk
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Store away from kids and pets.
