Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even after around ten years – the drop in lifting capacity is only ~1% (theoretically),
- They have excellent resistance to magnetism drop as a result of external magnetic sources,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of exact shaping as well as optimizing to individual applications,
- Key role in modern industrial fields – they are used in HDD drives, brushless drives, diagnostic systems, also modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength 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 advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these products are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- on a base made of structural steel, optimally conducting the magnetic flux
- with a cross-section no less than 10 mm
- characterized by lack of roughness
- with zero gap (no impurities)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces 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 drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
H&S for magnets
Eye protection
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Safe operation
Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and respect their power.
Precision electronics
A powerful magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet to high heat will destroy its magnetic structure and strength.
Electronic hazard
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Crushing force
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Pacemakers
Patients with a pacemaker should maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Machining danger
Dust created during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
Avoid contact if allergic
Certain individuals experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching may cause skin redness. We suggest use protective gloves.
Do not give to children
Absolutely keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are life-threatening.
