Strengths and weaknesses of rare earth magnets.
Advantages
- They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
- They are resistant to demagnetization induced by external field influence,
- Thanks to the shiny finish, the coating of nickel, gold-plated, or silver-plated gives an modern appearance,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Possibility of exact shaping as well as adjusting to atypical requirements,
- Fundamental importance in innovative solutions – they are used in magnetic memories, electric motors, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce 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 immune to moisture, in case of application outdoors
- Limited possibility of creating nuts in the magnet and complicated forms - recommended is cover - magnetic holder.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- with an polished touching surface
- under conditions of no distance (surface-to-surface)
- during detachment in a direction vertical to the mounting surface
- at standard ambient temperature
Determinants of lifting force in real conditions
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Steel type – mild steel attracts best. Alloy steels lower magnetic properties and holding force.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Warnings
Handling rules
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Impact on smartphones
Remember: rare earth magnets produce a field that confuses precision electronics. Keep a separation from your phone, tablet, and GPS.
Serious injuries
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Heat sensitivity
Do not overheat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Do not drill into magnets
Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Protective goggles
NdFeB magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets will cause them breaking into small pieces.
This is not a toy
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Keep away from kids and pets.
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Life threat
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Warning for allergy sufferers
A percentage of the population suffer from a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in an allergic reaction. We suggest use protective gloves.
