Advantages as well as disadvantages of rare earth magnets.
Benefits
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under close interference source,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in designing and the capacity to modify to specific needs,
- Huge importance in modern technologies – they are commonly used in computer drives, brushless drives, precision medical tools, as well as multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually 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.
- Plate material – mild steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (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 perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
Warnings
Powerful field
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Demagnetization risk
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Magnetic media
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Danger to the youngest
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are tragic.
Precision electronics
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Pinching danger
Big blocks can smash fingers instantly. Never put your hand between two attracting surfaces.
Warning for heart patients
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Magnet fragility
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Nickel allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
