Pros and cons of neodymium magnets.
Advantages
- They retain attractive force for almost ten years – the drop is just ~1% (in theory),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the shiny finish, the surface of nickel, gold-plated, or silver-plated gives an elegant appearance,
- Magnetic induction on the top side of the magnet is impressive,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in designing and the ability to customize to individual projects,
- Huge importance in innovative solutions – they are commonly used in mass storage devices, drive modules, advanced medical instruments, also complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of producing threads in the magnet and complex shapes - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- using a base made of high-permeability steel, serving as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by even structure
- with total lack of distance (no impurities)
- under perpendicular force direction (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Heat warning
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Powerful field
Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their power.
Physical harm
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
Health Danger
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Data carriers
Do not bring magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
This is not a toy
Always store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.
Allergic reactions
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them breaking into shards.
Fire risk
Powder created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Magnetic interference
Be aware: rare earth magnets produce a field that interferes with precision electronics. Keep a safe distance from your phone, tablet, and GPS.
