Pros as well as cons of rare earth magnets.
Advantages
- Their power remains stable, and after around ten years it decreases only by ~1% (theoretically),
- They retain their magnetic properties even under close interference source,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of accurate forming as well as adapting to concrete requirements,
- Huge importance in modern technologies – they find application in hard drives, electric motors, diagnostic systems, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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 complex shapes in magnets, we recommend using a housing - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- using a plate made of low-carbon steel, acting as a ideal flux conductor
- with a cross-section of at least 10 mm
- with a surface perfectly flat
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Determinants of lifting force in real conditions
- Air gap (between the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost to the other side.
- Plate material – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safe handling of NdFeB magnets
Respect the power
Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their force.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, immediately stop working with magnets and wear gloves.
Choking Hazard
Absolutely keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.
Threat to electronics
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Machining danger
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
ICD Warning
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Fragile material
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Serious injuries
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Keep away from electronics
Note: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, device, and navigation systems.
Demagnetization risk
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
