Strengths as well as weaknesses of neodymium magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They possess excellent resistance to magnetism drop when exposed to external fields,
- A magnet with a smooth silver surface looks better,
- Magnets have huge magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the potential of free shaping and adaptation to custom projects, NdFeB magnets can be produced in a variety of forms and dimensions, which makes them more universal,
- Huge importance in high-tech industry – they are used in HDD drives, motor assemblies, medical devices, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing 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 lose their power 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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of creating threads in the magnet and complex forms - preferred is casing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- characterized by smoothness
- with total lack of distance (without coatings)
- under axial application of breakaway force (90-degree angle)
- in stable room temperature
Magnet lifting force in use – key factors
- Distance – existence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly 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 lifting capacity (the magnet "punches through" it).
- Steel type – mild steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
Immense force
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Material brittleness
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets will cause them cracking into small pieces.
Fire risk
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Avoid contact if allergic
It is widely known that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact and choose encased magnets.
Swallowing risk
Always store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are tragic.
Health Danger
Patients with a ICD must maintain an large gap from magnets. The magnetic field can stop the operation of the implant.
Serious injuries
Big blocks can break fingers instantly. Under no circumstances put your hand between two strong magnets.
Heat sensitivity
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Keep away from electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Protect data
Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
