Strengths and weaknesses of rare earth magnets.
Strengths
- They retain magnetic properties for around ten years – the loss is just ~1% (according to analyses),
- They do not lose their magnetic properties even under strong external field,
- By applying a reflective layer of gold, the element presents an modern look,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to modularity in constructing and the ability to customize to individual projects,
- Versatile presence in electronics industry – they are commonly used in hard drives, brushless drives, precision medical tools, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- 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.
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complex forms - recommended is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- with total lack of distance (without paint)
- under axial application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost to the other side.
- Plate material – mild steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Medical interference
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Conscious usage
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Beware of splinters
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
Operating temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Bone fractures
Large magnets can smash fingers instantly. Do not place your hand betwixt two attracting surfaces.
GPS and phone interference
Be aware: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your phone, device, and navigation systems.
Magnetic media
Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Choking Hazard
Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Machining danger
Dust produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
