Advantages and disadvantages of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly resist against loss of magnetization caused by external fields,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the top side of the magnet turns out to be very high,
- 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...
- Possibility of precise machining and adjusting to individual needs,
- Universal use in electronics industry – they find application in computer drives, drive modules, medical equipment, also technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is higher than average,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Safe handling of neodymium magnets
Hand protection
Pinching hazard: The pulling power is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Respect the power
Use magnets consciously. Their huge power can shock even professionals. Plan your moves and respect their power.
Keep away from children
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Store away from kids and pets.
Implant safety
Individuals with a pacemaker have to keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
Beware of splinters
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Fire warning
Dust created during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop working with magnets and use protective gear.
Maximum temperature
Keep cool. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Threat to electronics
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
GPS Danger
Note: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
