Pros as well as cons of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They feature excellent resistance to magnetic field loss due to external fields,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are distinguished by maximum magnetic induction on the surface,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in shaping and the ability to adapt to individual projects,
- Significant place in electronics industry – they are utilized in magnetic memories, electromotive mechanisms, advanced medical instruments, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of creating threads in the magnet and complicated forms - recommended is cover - magnet mounting.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane cleaned and smooth
- with zero gap (no paint)
- during pulling in a direction perpendicular to the mounting surface
- in stable room temperature
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin steel does not close the flux, causing part of the power to be escaped to the other side.
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Conscious usage
Use magnets consciously. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their power.
Dust is flammable
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Electronic hazard
Data protection: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
GPS and phone interference
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Life threat
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Serious injuries
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Adults only
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from kids and pets.
Demagnetization risk
Monitor thermal conditions. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
