Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for around 10 years – the loss is just ~1% (according to analyses),
- Neodymium magnets remain remarkably resistant to demagnetization caused by external field sources,
- In other words, due to the metallic finish of nickel, the element gains visual value,
- Magnetic induction on the top side of the magnet remains exceptional,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Possibility of exact modeling and optimizing to atypical requirements,
- Significant place in innovative solutions – they are used in magnetic memories, electromotive mechanisms, diagnostic systems, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complicated forms in magnets, we propose using casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a base made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction vertical to the plane
- at ambient temperature room level
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material type – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.
Warnings
Dust is flammable
Dust generated during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Heat sensitivity
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Protective goggles
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.
Medical implants
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Choking Hazard
Neodymium magnets are not toys. Swallowing a few magnets can lead to them attracting across intestines, which poses a critical condition and necessitates immediate surgery.
Nickel allergy
A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to skin redness. We recommend use safety gloves.
Conscious usage
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Data carriers
Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
GPS Danger
A powerful magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.
Bone fractures
Large magnets can crush fingers in a fraction of a second. Do not put your hand between two strong magnets.
