Pros and cons of neodymium magnets.
Pros
- Their magnetic field is durable, and after around ten years it decreases only by ~1% (theoretically),
- Neodymium magnets are characterized by extremely resistant to loss of magnetic properties caused by external field sources,
- By applying a shiny layer of silver, the element presents an nice look,
- Magnetic induction on the top side of the magnet remains very high,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual creating as well as adapting to atypical needs,
- Wide application in innovative solutions – they are used in HDD drives, electromotive mechanisms, diagnostic systems, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in compact constructions
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic mount, due to difficulties in creating threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of low-carbon steel, serving as a magnetic yoke
- whose thickness equals approx. 10 mm
- with a surface free of scratches
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface structure – the smoother and more polished the surface, 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 thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Threat to navigation
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Heat sensitivity
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.
Material brittleness
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them cracking into shards.
Physical harm
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Threat to electronics
Avoid bringing magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Swallowing risk
Neodymium magnets are not suitable for play. Eating multiple magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
ICD Warning
Patients with a pacemaker have to keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Warning for allergy sufferers
Some people experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Prolonged contact can result in a rash. We strongly advise wear safety gloves.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Fire warning
Dust generated during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
