Pros and cons of neodymium magnets.
Pros
- Their strength is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of accurate forming as well as optimizing to precise applications,
- Fundamental importance in future technologies – they find application in magnetic memories, brushless drives, medical devices, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose 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. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing threads and complicated forms in magnets, we recommend using casing - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Furthermore, small components of these products can disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- with a cross-section minimum 10 mm
- with an ideally smooth contact surface
- without the slightest insulating layer between the magnet and steel
- under vertical force direction (90-degree angle)
- at temperature room level
Practical lifting capacity: influencing factors
- Distance (betwixt the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Cards and drives
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Threat to navigation
Be aware: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Caution required
Handle with care. Rare earth magnets attract from a distance and connect with massive power, often faster than you can move away.
Adults only
Adult use only. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Bodily injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
Thermal limits
Do not overheat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Fire risk
Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Allergic reactions
A percentage of the population suffer from a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to dermatitis. We recommend use protective gloves.
Medical interference
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Magnet fragility
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
