Pros as well as cons of rare earth magnets.
Pros
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They are resistant to demagnetization induced by external field influence,
- Thanks to the elegant finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
- They show high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Due to the option of precise molding and adaptation to specialized projects, NdFeB magnets can be modeled in a variety of forms and dimensions, which increases their versatility,
- Universal use in advanced technology sectors – they are used in computer drives, motor assemblies, precision medical tools, as well as technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complicated shapes in magnets, we propose using casing - magnetic mechanism.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a sheet made of high-permeability steel, functioning as a ideal flux conductor
- whose thickness reaches at least 10 mm
- with a surface free of scratches
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Air gap (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate does not accept the full field, causing part of the power to be lost to the other side.
- Plate material – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Threat to navigation
Be aware: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
Safe distance
Do not bring magnets close to a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
Do not drill into magnets
Machining of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Do not give to children
Absolutely keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them cracking into shards.
Health Danger
Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Permanent damage
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Handling rules
Handle with care. Rare earth magnets act from a distance and snap with massive power, often faster than you can move away.
Pinching danger
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
