Strengths and weaknesses of rare earth magnets.
Strengths
- Their strength is maintained, and after around ten years it decreases only by ~1% (according to research),
- Neodymium magnets are distinguished by highly resistant to demagnetization caused by external field sources,
- A magnet with a shiny gold surface has an effective appearance,
- Magnets have excellent magnetic induction on the active area,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in shaping and the ability to modify to complex applications,
- Key role in innovative solutions – they are commonly used in mass storage devices, electric motors, medical devices, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complicated shapes - recommended is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of low-carbon steel, acting as a circuit closing element
- with a thickness of at least 10 mm
- with an polished contact surface
- with direct contact (no impurities)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Air gap (betwixt the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust 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 nominal value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Medical interference
Individuals with a heart stimulator have to maintain an safe separation from magnets. The magnetism can stop the functioning of the implant.
Finger safety
Danger of trauma: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Impact on smartphones
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Keep away from computers
Very strong magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Heat warning
Keep cool. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Keep away from children
Adult use only. Small elements can be swallowed, causing severe trauma. Store out of reach of children and animals.
Flammability
Dust produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Eye protection
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Warning for allergy sufferers
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, immediately stop working with magnets and use protective gear.
Handling guide
Exercise caution. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can move away.
