Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even over around ten years – the drop in lifting capacity is only ~1% (theoretically),
- Magnets effectively protect themselves against demagnetization caused by foreign field sources,
- A magnet with a smooth gold surface has an effective appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Due to the potential of flexible forming and adaptation to individualized needs, NdFeB magnets can be manufactured in a broad palette of shapes and sizes, which increases their versatility,
- Universal use in modern industrial fields – they find application in computer drives, drive modules, medical devices, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 possibility of creating threads in the magnet and complicated forms - preferred is a housing - magnet mounting.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these products can disrupt the diagnostic process 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 force for a neodymium magnet – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic field
- with a thickness no less than 10 mm
- with a plane cleaned and smooth
- with direct contact (without paint)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be wasted to the other side.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Respect the power
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Beware of splinters
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Magnetic interference
GPS units and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Choking Hazard
Absolutely store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are fatal.
Data carriers
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Bodily injuries
Big blocks can smash fingers in a fraction of a second. Never put your hand between two strong magnets.
Heat sensitivity
Monitor thermal conditions. Heating the magnet to high heat will destroy its magnetic structure and strength.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Combustion hazard
Dust produced during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Implant safety
People with a pacemaker have to maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
