Strengths and weaknesses of rare earth magnets.
Strengths
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- By covering with a reflective layer of gold, the element gains an nice look,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of detailed creating and optimizing to atypical conditions,
- Universal use in modern industrial fields – they are used in computer drives, electromotive mechanisms, advanced medical instruments, also modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- They are fragile upon too strong 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 force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- with a cross-section no less than 10 mm
- with a plane cleaned and smooth
- with zero gap (no coatings)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Clearance – existence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be lost into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Do not drill into magnets
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Immense force
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Allergic reactions
Studies show that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, prevent touching magnets with bare hands and select encased magnets.
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.
Implant safety
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Threat to electronics
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Thermal limits
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Serious injuries
Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
GPS and phone interference
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Danger to the youngest
Always store magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.
