Pros and cons of rare earth magnets.
Strengths
- They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by external interference,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Considering the potential of accurate molding and adaptation to individualized projects, NdFeB magnets can be produced in a variety of shapes and sizes, which expands the range of possible applications,
- Versatile presence in modern industrial fields – they serve a role in HDD drives, electric drive systems, medical equipment, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose power 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic field
- whose thickness equals approx. 10 mm
- with an ground contact surface
- with direct contact (without impurities)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may attract less.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the holding force.
H&S for magnets
Magnetic interference
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Handling guide
Before starting, 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 ruin its magnetic structure and strength.
Cards and drives
Avoid bringing magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Flammability
Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Danger to pacemakers
People with a ICD have to keep an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Choking Hazard
Only for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.
Avoid contact if allergic
It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, prevent touching magnets with bare hands and opt for encased magnets.
Pinching danger
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.
