Advantages and disadvantages of neodymium magnets.
Strengths
- They do not lose strength, even during around ten years – the decrease in power is only ~1% (based on measurements),
- Magnets perfectly defend themselves against loss of magnetization caused by external fields,
- Thanks to the elegant finish, the surface of nickel, gold, or silver gives an clean appearance,
- Magnets have maximum magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to versatility in constructing and the ability to customize to specific needs,
- Versatile presence in modern industrial fields – they are utilized in data components, electric drive systems, medical devices, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose force 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 extremely resistant to heat
- 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 prevent oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complicated forms - preferred is a housing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- with a surface free of scratches
- with total lack of distance (no paint)
- for force acting at a right angle (in the magnet axis)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Warnings
Impact on smartphones
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
Do not overheat magnets
Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Fire risk
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Safe operation
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Eye protection
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Crushing risk
Danger of trauma: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Do not give to children
Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop working with magnets and wear gloves.
Safe distance
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
