Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- Magnets effectively resist against demagnetization caused by external fields,
- A magnet with a shiny gold surface has better aesthetics,
- Magnetic induction on the working layer of the magnet turns out to be strong,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of individual forming and modifying to individual conditions,
- Versatile presence in advanced technology sectors – they are used in computer drives, brushless drives, medical equipment, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of creating threads in the magnet and complicated forms - recommended is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of mild steel, functioning as a circuit closing element
- with a cross-section minimum 10 mm
- characterized by smoothness
- with zero gap (no paint)
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Determinants of lifting force in real conditions
- Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be escaped to the other side.
- Steel type – mild steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Life threat
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Magnet fragility
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.
Finger safety
Danger of trauma: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Product not for children
Only for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from children and animals.
Keep away from electronics
An intense magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a device to prevent breaking the sensors.
Avoid contact if allergic
Some people experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling may cause an allergic reaction. It is best to use protective gloves.
Machining danger
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Data carriers
Intense magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Immense force
Handle magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their force.
