Pros as well as cons of rare earth magnets.
Strengths
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
- By applying a smooth layer of silver, the element acquires an nice look,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the potential of accurate forming and adaptation to unique needs, NdFeB magnets can be produced in a wide range of forms and dimensions, which expands the range of possible applications,
- Key role in modern industrial fields – they serve a role in magnetic memories, electric motors, precision medical tools, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using a housing - magnetic holder.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- using a sheet made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a surface free of scratches
- with total lack of distance (no impurities)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature room level
What influences lifting capacity in practice
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Heat warning
Avoid heat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop handling magnets and use protective gear.
Product not for children
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of children and animals.
Hand protection
Large magnets can break fingers instantly. Do not place your hand betwixt two strong magnets.
Health Danger
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Data carriers
Do not bring magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Magnetic interference
A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Maintain magnets near a device to prevent breaking the sensors.
Risk of cracking
NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them cracking into shards.
Handling guide
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Machining danger
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
