Advantages and disadvantages of rare earth magnets.
Benefits
- They do not lose strength, even after around 10 years – the drop in power is only ~1% (according to tests),
- Neodymium magnets remain highly resistant to magnetic field loss caused by external magnetic fields,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets are characterized by extremely high magnetic induction on the working surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Thanks to modularity in forming and the ability to modify to unusual requirements,
- Fundamental importance in modern industrial fields – they are used in data components, electromotive mechanisms, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using a housing - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Distance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be wasted into the air.
- Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Warnings
Implant safety
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness happens, cease working with magnets and wear gloves.
Data carriers
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
Threat to navigation
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Immense force
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
No play value
NdFeB magnets are not suitable for play. Eating a few magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.
Heat sensitivity
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Dust explosion hazard
Dust created during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Hand protection
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.
Magnet fragility
Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them breaking into shards.
