Pros and cons of neodymium magnets.
Pros
- Their power remains stable, and after approximately ten years it decreases only by ~1% (according to research),
- They are noted for resistance to demagnetization induced by external disturbances,
- A magnet with a metallic nickel surface looks better,
- Magnetic induction on the working part of the magnet remains extremely intense,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of detailed creating and modifying to specific requirements,
- Versatile presence in future technologies – they find application in HDD drives, electric drive systems, medical equipment, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a base made of high-permeability steel, serving as a circuit closing element
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- without any clearance between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Gap (betwixt the magnet and the plate), since even a microscopic 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).
- Angle of force application – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Plate material – mild steel attracts best. Higher carbon content reduce magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Allergic reactions
Certain individuals experience a contact allergy to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to a rash. We suggest wear protective gloves.
Cards and drives
Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Dust explosion hazard
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Health Danger
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Physical harm
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Heat sensitivity
Watch the temperature. Heating the magnet to high heat will destroy its properties and pulling force.
Protective goggles
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Adults only
Strictly keep magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Magnetic interference
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Handling rules
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
