Pros as well as cons of rare earth magnets.
Strengths
- They do not lose strength, even during nearly 10 years – the decrease in strength is only ~1% (based on measurements),
- They do not lose their magnetic properties even under strong external field,
- In other words, due to the aesthetic finish of nickel, the element is aesthetically pleasing,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the ability of free shaping and customization to unique solutions, NdFeB magnets can be created in a variety of geometric configurations, which increases their versatility,
- Versatile presence in high-tech industry – they are utilized in hard drives, drive modules, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their strength 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. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.
Warnings
Immense force
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
No play value
Always store magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are life-threatening.
Material brittleness
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease handling magnets and use protective gear.
Hand protection
Pinching hazard: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Maximum temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its properties and strength.
Machining danger
Powder generated during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Data carriers
Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Keep away from electronics
Be aware: neodymium magnets generate a field that confuses precision electronics. Keep a separation from your phone, device, and navigation systems.
Danger to pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
