Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They retain attractive force for nearly 10 years – the loss is just ~1% (according to analyses),
- They are resistant to demagnetization induced by external magnetic fields,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are characterized by very high magnetic induction on the outer layer,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of exact modeling as well as modifying to defined needs,
- Wide application in modern technologies – they are utilized in magnetic memories, motor assemblies, diagnostic systems, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by even structure
- with zero gap (without paint)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
What influences lifting capacity in practice
- Clearance – the presence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Safe handling of neodymium magnets
Flammability
Dust generated during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Protect data
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, cease working with magnets and wear gloves.
Keep away from children
Strictly keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
Material brittleness
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Operating temperature
Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and pulling force.
Phone sensors
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, device, and GPS.
Warning for heart patients
Individuals with a heart stimulator must maintain an large gap from magnets. The magnetic field can disrupt the operation of the implant.
Pinching danger
Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Powerful field
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
