Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They have excellent resistance to magnetic field loss as a result of external magnetic sources,
- Thanks to the smooth finish, the plating of nickel, gold, or silver-plated gives an clean appearance,
- Magnetic induction on the top side of the magnet remains strong,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
- Possibility of precise machining as well as optimizing to complex applications,
- Huge importance in modern industrial fields – they serve a role in data components, electric drive systems, precision medical tools, also complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- At 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.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a plate made of structural steel, effectively closing the magnetic flux
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction vertical to the plane
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick steel does not close the flux, causing part of the power to be escaped to the other side.
- Steel type – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Product not for children
Only for adults. Small elements can be swallowed, causing serious injuries. Store away from children and animals.
Avoid contact if allergic
It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact or opt for encased magnets.
Caution required
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Beware of splinters
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.
Warning for heart patients
People with a ICD have to maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Electronic hazard
Device Safety: Strong magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Finger safety
Risk of injury: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Keep away from electronics
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Flammability
Powder created during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
