Other proposals
Pros as well as cons of rare earth magnets.
Pros
- Their strength remains stable, and after around 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets prove to be highly resistant to magnetic field loss caused by external interference,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in designing and the ability to adapt to complex applications,
- Universal use in modern industrial fields – they serve a role in hard drives, drive modules, advanced medical instruments, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these magnets are able to be problematic in diagnostics 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 affects it?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a surface free of scratches
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material composition – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Choking Hazard
NdFeB magnets are not toys. Accidental ingestion of several magnets may result in them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Safe operation
Handle magnets with awareness. Their immense force can surprise even experienced users. Stay alert and respect their power.
Compass and GPS
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Warning for heart patients
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Eye protection
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Cards and drives
Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Do not overheat magnets
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Allergic reactions
Medical facts indicate that nickel (the usual finish) is a common allergen. If you have an allergy, prevent direct skin contact or select coated magnets.
Serious injuries
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
