Pros and cons of rare earth magnets.
Strengths
- They do not lose magnetism, even over nearly ten years – the decrease in power is only ~1% (theoretically),
- They show high resistance to demagnetization induced by external magnetic fields,
- By using a shiny coating of silver, the element presents an modern look,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of exact shaping as well as adapting to specific conditions,
- Fundamental importance in electronics industry – they are commonly used in computer drives, electric motors, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB 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 oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small components of these products can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a plate made of mild steel, acting as a magnetic yoke
- whose thickness equals approx. 10 mm
- characterized by even structure
- without any insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Key elements affecting lifting force
- Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force 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 limits the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Cards and drives
Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Handling guide
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Product not for children
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.
GPS Danger
A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a device to avoid breaking the sensors.
Serious injuries
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Thermal limits
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Pacemakers
Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Eye protection
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Nickel allergy
Certain individuals suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. It is best to wear safety gloves.
Fire warning
Powder created during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
