Advantages as well as disadvantages of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by external disturbances,
- In other words, due to the smooth finish of silver, the element gains a professional look,
- Magnetic induction on the top side of the magnet remains impressive,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of detailed shaping as well as modifying to specific requirements,
- Versatile presence in advanced technology sectors – they are used in mass storage devices, brushless drives, precision medical tools, and multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making nuts in the magnet and complicated forms - preferred is cover - magnet mounting.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these products 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
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a base made of high-permeability steel, acting as a circuit closing element
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- without any clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Air gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel type – mild steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Warnings
Sensitization to coating
Certain individuals suffer from a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to skin redness. We suggest wear protective gloves.
Physical harm
Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Cards and drives
Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
This is not a toy
These products are not toys. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Permanent damage
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Threat to navigation
Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Safe operation
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Mechanical processing
Powder produced during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Shattering risk
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
Health Danger
Patients with a heart stimulator must maintain an safe separation from magnets. The magnetism can disrupt the operation of the implant.
