Pros and cons of neodymium magnets.
Advantages
- Their power remains stable, and after around 10 years it decreases only by ~1% (theoretically),
- They show high resistance to demagnetization induced by external field influence,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets exhibit excellent magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise forming as well as optimizing to concrete conditions,
- Universal use in modern industrial fields – they find application in computer drives, electric motors, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- whose thickness equals approx. 10 mm
- with an ground contact surface
- without any air gap between the magnet and steel
- during detachment in a direction vertical to the plane
- at temperature room level
Determinants of lifting force in real conditions
- Air gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy steels lower magnetic permeability and holding force.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Safe handling of neodymium magnets
Operating temperature
Watch the temperature. Exposing the magnet to high heat will ruin its properties and strength.
Beware of splinters
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
Skin irritation risks
Some people have a sensitization to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause an allergic reaction. It is best to wear safety gloves.
Bodily injuries
Big blocks can break fingers in a fraction of a second. Do not place your hand between two strong magnets.
Adults only
Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of children and animals.
Threat to navigation
Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Fire risk
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Electronic hazard
Do not bring magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Immense force
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Medical implants
Patients with a pacemaker should maintain an safe separation from magnets. The magnetic field can stop the functioning of the implant.
