Strengths as well as weaknesses of neodymium magnets.
Advantages
- They do not lose magnetism, even after approximately ten years – the decrease in strength is only ~1% (according to tests),
- They possess excellent resistance to magnetic field loss due to external fields,
- By using a decorative layer of silver, the element acquires an professional look,
- They feature high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- In view of the option of accurate molding and customization to unique needs, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which expands the range of possible applications,
- Fundamental importance in modern industrial fields – they are used in hard drives, drive modules, precision medical tools, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures 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 secure oxidation and corrosion.
- Due to limitations in creating nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- whose transverse dimension is min. 10 mm
- characterized by smoothness
- with zero gap (no impurities)
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Space between surfaces – 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 – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the flux to be lost to the other side.
- Plate material – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Base smoothness – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
Respect the power
Be careful. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can move away.
Shattering risk
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them breaking into small pieces.
Electronic hazard
Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Threat to navigation
A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets near a smartphone to prevent breaking the sensors.
Bone fractures
Large magnets can break fingers instantly. Never put your hand between two strong magnets.
Do not overheat magnets
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Adults only
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.
Danger to pacemakers
Patients with a pacemaker have to maintain an large gap from magnets. The magnetism can stop the operation of the implant.
Dust is flammable
Dust produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
