Strengths as well as weaknesses of rare earth magnets.
Pros
- They do not lose strength, even during approximately 10 years – the drop in strength is only ~1% (based on measurements),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external field sources,
- By applying a reflective coating of gold, the element acquires an proper look,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the ability of free shaping and adaptation to specialized requirements, NdFeB magnets can be produced in a broad palette of forms and dimensions, which increases their versatility,
- Significant place in advanced technology sectors – they find application in data components, electric drive systems, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- with a thickness no less than 10 mm
- characterized by smoothness
- with total lack of distance (without paint)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Clearance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be lost to the other side.
- Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
Physical harm
Danger of trauma: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Choking Hazard
Strictly keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.
Magnets are brittle
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Precision electronics
GPS units and mobile phones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Dust is flammable
Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Electronic hazard
Do not bring magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Handling rules
Handle magnets consciously. Their powerful strength can surprise even experienced users. Stay alert and respect their power.
Do not overheat magnets
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Health Danger
Patients with a heart stimulator must keep an large gap from magnets. The magnetism can disrupt the operation of the life-saving device.
