Pros as well as cons of Nd2Fe14B magnets.
Pros
- They retain attractive force for almost ten years – the drop is just ~1% (in theory),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnetic induction on the working layer of the magnet is impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- In view of the ability of precise molding and customization to unique solutions, magnetic components can be created in a broad palette of forms and dimensions, which expands the range of possible applications,
- Huge importance in modern industrial fields – they are used in computer drives, electric motors, precision medical tools, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a thickness minimum 10 mm
- with an ideally smooth contact surface
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Gap (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Keep away from children
Strictly store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are life-threatening.
Compass and GPS
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Magnetic media
Intense magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Caution required
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Crushing risk
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Allergy Warning
Studies show that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or choose coated magnets.
Beware of splinters
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Medical interference
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Fire warning
Dust created during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
