Pros and cons of Nd2Fe14B magnets.
Strengths
- Their strength remains stable, and after around 10 years it drops only by ~1% (according to research),
- They have excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- By applying a smooth coating of gold, the element acquires an modern look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Considering the option of flexible molding and customization to custom requirements, NdFeB magnets can be manufactured in a wide range of geometric configurations, which makes them more universal,
- Significant place in modern technologies – they are utilized in hard drives, brushless drives, medical devices, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- 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.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complex shapes - recommended is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these products can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a base made of low-carbon steel, serving as a magnetic yoke
- with a cross-section no less than 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- in stable room temperature
Practical aspects of lifting capacity – factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 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.
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost into the air.
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Do not give to children
Absolutely store magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.
Magnetic media
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Power loss in heat
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.
Machining danger
Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Life threat
Warning for patients: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Safe operation
Use magnets with awareness. Their huge power can surprise even professionals. Plan your moves and do not underestimate their power.
Protective goggles
Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Compass and GPS
A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Do not bring magnets close to a device to prevent breaking the sensors.
Finger safety
Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Allergic reactions
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and choose encased magnets.
