Strengths as well as weaknesses of neodymium magnets.
Pros
- They do not lose magnetism, even during around 10 years – the decrease in strength is only ~1% (theoretically),
- Neodymium magnets prove to be remarkably resistant to demagnetization caused by external field sources,
- A magnet with a shiny nickel surface has better aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to flexibility in designing and the ability to modify to complex applications,
- Fundamental importance in innovative solutions – they are used in hard drives, drive modules, medical devices, and technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complex shapes in magnets, we recommend using casing - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- using a base made of low-carbon steel, acting as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an ground contact surface
- under conditions of ideal adhesion (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Skin irritation risks
Certain individuals have a sensitization to nickel, which is the standard coating for neodymium magnets. Prolonged contact might lead to dermatitis. We strongly advise wear protective gloves.
Handling guide
Handle with care. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can react.
Medical interference
People with a heart stimulator must maintain an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
Combustion hazard
Dust created during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Electronic devices
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Impact on smartphones
A strong magnetic field interferes with the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Protective goggles
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Do not overheat magnets
Control the heat. Heating the magnet to high heat will ruin its properties and strength.
Hand protection
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Product not for children
These products are not intended for children. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and requires urgent medical intervention.
