Advantages as well as disadvantages of neodymium magnets.
Pros
- They retain attractive force for almost ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets are extremely resistant to loss of magnetic properties caused by external field sources,
- By applying a smooth coating of nickel, the element gains an elegant look,
- Magnetic induction on the working layer of the magnet is extremely intense,
- 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 exact forming and optimizing to atypical needs,
- Significant place in advanced technology sectors – they find application in data components, electric drive systems, medical devices, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- 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 protecting against moisture
- We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by even structure
- under conditions of no distance (metal-to-metal)
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Health Danger
Patients with a heart stimulator have to keep an large gap from magnets. The magnetic field can stop the functioning of the implant.
Machining danger
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Physical harm
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
No play value
These products are not toys. Swallowing several magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Respect the power
Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can react.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Magnetic interference
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Protective goggles
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Protect data
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
