Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by external field sources,
- Thanks to the metallic finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- Magnets exhibit excellent magnetic induction on the outer layer,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in designing and the capacity to modify to client solutions,
- Versatile presence in modern industrial fields – they are used in magnetic memories, electromotive mechanisms, precision medical tools, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of creating threads in the magnet and complicated forms - preferred is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- with an polished contact surface
- with zero gap (without impurities)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature room level
Determinants of lifting force in real conditions
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be escaped to the other side.
- Steel type – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
This is not a toy
NdFeB magnets are not intended for children. Eating multiple magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.
Magnets are brittle
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Machining danger
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Crushing force
Protect your hands. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Be careful!
Warning for allergy sufferers
Studies show that nickel (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact and select encased magnets.
Protect data
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Handling rules
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Phone sensors
GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Maximum temperature
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Health Danger
Individuals with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.
