Pros and cons of rare earth magnets.
Benefits
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They show high resistance to demagnetization induced by external disturbances,
- Thanks to the shimmering finish, the plating of nickel, gold, or silver-plated gives an aesthetic appearance,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in constructing and the ability to customize to unusual requirements,
- Universal use in future technologies – they are commonly used in mass storage devices, electromotive mechanisms, medical devices, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be lost to the other side.
- Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
Hand protection
Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Handling rules
Handle magnets with awareness. Their immense force can shock even professionals. Stay alert and do not underestimate their power.
Warning for allergy sufferers
Studies show that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact and opt for coated magnets.
Combustion hazard
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Life threat
Patients with a ICD have to maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Protective goggles
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Data carriers
Very strong magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Impact on smartphones
A powerful magnetic field disrupts the functioning of compasses in phones and GPS navigation. Keep magnets near a device to avoid damaging the sensors.
Demagnetization risk
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Choking Hazard
Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.
