Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They retain full power for nearly ten years – the loss is just ~1% (in theory),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- A magnet with a metallic nickel surface has better aesthetics,
- Magnets possess excellent magnetic induction on the working surface,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to flexibility in constructing and the capacity to modify to specific needs,
- Huge importance in electronics industry – they are used in magnetic memories, drive modules, medical equipment, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- without any clearance between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Skin irritation risks
A percentage of the population experience a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to a rash. We recommend wear protective gloves.
Eye protection
Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them cracking into shards.
ICD Warning
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Finger safety
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Combustion hazard
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Demagnetization risk
Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Conscious usage
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Phone sensors
A powerful magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Keep away from children
Neodymium magnets are not intended for children. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires immediate surgery.
Safe distance
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
