Pros and cons of neodymium magnets.
Strengths
- They do not lose magnetism, even after nearly 10 years – the drop in power is only ~1% (based on measurements),
- Neodymium magnets prove to be highly resistant to magnetic field loss caused by external interference,
- In other words, due to the smooth finish of nickel, the element gains visual value,
- Magnets are distinguished by extremely high magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Due to the option of free molding and adaptation to custom projects, neodymium magnets can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Universal use in high-tech industry – they serve a role in computer drives, brushless drives, precision medical tools, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their force 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these magnets are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- with total lack of distance (without paint)
- under axial force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Air gap (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, rust or debris).
- Direction of force – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be wasted to the other side.
- Material type – the best choice is high-permeability steel. Cast iron may attract less.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.
Safe handling of neodymium magnets
Pacemakers
Patients with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.
Magnetic interference
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Handling rules
Use magnets consciously. Their immense force can surprise even professionals. Be vigilant and respect their power.
Magnetic media
Equipment safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Choking Hazard
Always keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are tragic.
Heat warning
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Fire warning
Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Allergic reactions
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Physical harm
Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
