Advantages as well as disadvantages of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They possess excellent resistance to magnetic field loss due to external magnetic sources,
- By covering with a shiny coating of nickel, the element acquires an proper look,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Thanks to versatility in forming and the ability to adapt to unusual requirements,
- Versatile presence in innovative solutions – they are utilized in HDD drives, electric motors, precision medical tools, as well as industrial machines.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend 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, as well as 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 recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in producing threads and complex shapes in magnets, we propose using cover - magnetic mount.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these products can be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension reaches at least 10 mm
- with an polished touching surface
- with zero gap (without paint)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Practical aspects of lifting capacity – factors
- Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
This is not a toy
Always keep magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.
Keep away from computers
Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Risk of cracking
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
Hand protection
Danger of trauma: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Conscious usage
Use magnets consciously. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.
Phone sensors
Note: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your phone, tablet, and GPS.
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Warning for heart patients
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Fire warning
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Permanent damage
Keep cool. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
