Advantages as well as disadvantages of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They retain their magnetic properties even under external field action,
- In other words, due to the shiny layer of silver, the element looks attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Thanks to the ability of precise forming and adaptation to unique requirements, neodymium magnets can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Huge importance in modern industrial fields – they find application in computer drives, electric motors, medical devices, and other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making threads in the magnet and complex shapes - recommended is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with an polished touching surface
- with direct contact (without impurities)
- under axial force direction (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Steel grade – ideal substrate is pure iron steel. Cast iron may attract less.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Adults only
Only for adults. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of kids and pets.
ICD Warning
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Magnet fragility
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Fire warning
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Nickel coating and allergies
Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact or choose coated magnets.
Conscious usage
Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
GPS and phone interference
An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.
Bone fractures
Large magnets can break fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Protect data
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Maximum temperature
Do not overheat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
