Advantages as well as disadvantages of rare earth magnets.
Pros
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets are distinguished by highly resistant to magnetic field loss caused by magnetic disturbances,
- By covering with a reflective coating of silver, the element gains an proper look,
- Magnetic induction on the working layer of the magnet remains extremely intense,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the possibility of precise molding and customization to unique projects, NdFeB magnets can be produced in a broad palette of shapes and sizes, which makes them more universal,
- Universal use in modern technologies – they are used in computer drives, electric motors, diagnostic systems, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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 corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- using a base made of high-permeability steel, acting as a circuit closing element
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- without any air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or dirt).
- 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.
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be escaped to the other side.
- Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the holding force.
H&S for magnets
Handling guide
Be careful. Rare earth magnets act from a long distance and snap with huge force, often faster than you can move away.
Choking Hazard
These products are not toys. Swallowing several magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.
Permanent damage
Do not overheat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Machining danger
Dust generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Allergy Warning
Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands and select coated magnets.
Medical interference
People with a ICD have to keep an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.
Keep away from computers
Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Keep away from electronics
An intense magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Eye protection
NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them cracking into small pieces.
Bodily injuries
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.
