Advantages and disadvantages of rare earth magnets.
Strengths
- They do not lose magnetism, even during around ten years – the drop in strength is only ~1% (based on measurements),
- They retain their magnetic properties even under strong external field,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Due to the potential of accurate forming and customization to individualized requirements, magnetic components can be created in a variety of forms and dimensions, which amplifies use scope,
- Fundamental importance in electronics industry – they are utilized in mass storage devices, electric motors, medical devices, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- on a block made of mild steel, optimally conducting the magnetic flux
- with a thickness of at least 10 mm
- with a plane perfectly flat
- with zero gap (no paint)
- during detachment in a direction perpendicular to the plane
- in stable room temperature
Practical aspects of lifting capacity – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the load capacity.
H&S for magnets
Danger to pacemakers
People with a ICD must keep an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
Keep away from computers
Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Precision electronics
A strong magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Heat warning
Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Physical harm
Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
Risk of cracking
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them shattering into small pieces.
Flammability
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Do not underestimate power
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Do not give to children
Always store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Nickel coating and allergies
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease working with magnets and use protective gear.
