Strengths as well as weaknesses of neodymium magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They feature excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- In other words, due to the reflective finish of gold, the element gains a professional look,
- Magnets are distinguished by exceptionally strong magnetic induction on the surface,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the option of accurate forming and adaptation to individualized requirements, NdFeB magnets can be produced in a variety of forms and dimensions, which increases their versatility,
- Huge importance in electronics industry – they find application in mass storage devices, electromotive mechanisms, medical devices, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- Neodymium magnets decrease their strength 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complicated forms in magnets, we recommend using casing - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices can 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
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- 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
- characterized by smoothness
- without the slightest clearance between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped to the other side.
- Steel type – low-carbon steel gives the best results. Alloy admixtures lower magnetic permeability and holding force.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safe handling of neodymium magnets
Serious injuries
Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two strong magnets.
Medical interference
For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Dust explosion hazard
Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Powerful field
Handle magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their force.
Avoid contact if allergic
Studies show that the nickel plating (the usual finish) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands or choose versions in plastic housing.
Adults only
Neodymium magnets are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.
Phone sensors
A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets close to a smartphone to prevent damaging the sensors.
Protective goggles
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Magnetic media
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Power loss in heat
Do not overheat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
