Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their remarkable strength, neodymium magnets offer the following advantages:
- They virtually do not lose strength, because even after ten years, the performance loss is only ~1% (based on calculations),
- They show exceptional resistance to demagnetization from outside magnetic sources,
- By applying a reflective layer of nickel, the element gains a sleek look,
- They exhibit superior levels of magnetic induction near the outer area of the magnet,
- With the right combination of magnetic alloys, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the form),
- The ability for custom shaping and adjustment to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
- Important function in modern technologies – they serve a purpose in hard drives, rotating machines, medical equipment along with technologically developed systems,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of neodymium magnets:
- They can break when subjected to a heavy impact. If the magnets are exposed to mechanical hits, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture while also enhances its overall resistance,
- They lose field intensity at high temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Magnets exposed to moisture can rust. Therefore, for outdoor applications, we suggest waterproof types made of rubber,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing holes directly in the magnet,
- Health risk due to small fragments may arise, when consumed by mistake, which is notable in the context of child safety. Additionally, minuscule fragments from these magnets have the potential to complicate medical imaging if inside the body,
- High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which may limit large-scale applications
Magnetic strength at its maximum – what contributes to it?
The given pulling force of the magnet represents the maximum force, calculated in a perfect environment, that is:
- with mild steel, serving as a magnetic flux conductor
- of a thickness of at least 10 mm
- with a refined outer layer
- in conditions of no clearance
- with vertical force applied
- in normal thermal conditions
Lifting capacity in practice – influencing factors
In practice, the holding capacity of a magnet is affected by these factors, from crucial to less important:
- Air gap between the magnet and the plate, since even a very small distance (e.g. 0.5 mm) can cause a drop in lifting force of up to 50%.
- Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
- Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
- Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
- Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
- Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.
* Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance {between} the magnet’s surface and the plate decreases the holding force.
Safety Precautions
Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can shock you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
If have a finger between or alternatively on the path of attracting magnets, there may be a severe cut or a fracture.
Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
The magnet coating is made of nickel, so be cautious if you have an allergy.
Studies show a small percentage of people have allergies to certain metals, including nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets should not be near people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Magnets made of neodymium are known for being fragile, which can cause them to become damaged.
Neodymium magnetic are delicate as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
