Pros and cons of rare earth magnets.
Advantages
- They do not lose power, even during around ten years – the drop in power is only ~1% (according to tests),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by magnetic disturbances,
- Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of accurate creating as well as modifying to complex conditions,
- Key role in advanced technology sectors – they are utilized in hard drives, drive modules, diagnostic systems, as well as technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's 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 advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these devices can complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Magnetic strength at its maximum – what contributes to it?
- on a block made of structural steel, effectively closing the magnetic flux
- with a cross-section minimum 10 mm
- with a surface free of scratches
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be lost into the air.
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate lowers the load capacity.
Warnings
Power loss in heat
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Electronic devices
Do not bring magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Pacemakers
Individuals with a ICD should keep an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
GPS Danger
Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Physical harm
Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Danger to the youngest
NdFeB magnets are not toys. Eating several magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop working with magnets and use protective gear.
Risk of cracking
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Flammability
Powder created during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Respect the power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
