Strengths and weaknesses of neodymium magnets.
Advantages
- They do not lose power, even after nearly ten years – the reduction in power is only ~1% (theoretically),
- They maintain their magnetic properties even under close interference source,
- By covering with a lustrous coating of nickel, the element acquires an elegant look,
- Magnetic induction on the working layer of the magnet remains maximum,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
- Thanks to flexibility in designing and the ability to customize to individual projects,
- Versatile presence in modern industrial fields – they serve a role in data components, brushless drives, medical devices, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems
Cons
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of creating threads in the magnet and complex shapes - recommended is casing - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key 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.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- whose thickness is min. 10 mm
- with a plane perfectly flat
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Allergic reactions
Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact and choose encased magnets.
Fire risk
Powder created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Material brittleness
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
GPS Danger
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Warning for heart patients
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Permanent damage
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Powerful field
Handle magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their power.
Choking Hazard
Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are life-threatening.
Safe distance
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Serious injuries
Protect your hands. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
