Advantages as well as disadvantages of rare earth magnets.
Advantages
- They do not lose strength, even after nearly ten years – the decrease in strength is only ~1% (based on measurements),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by magnetic disturbances,
- Thanks to the glossy finish, the surface of nickel, gold-plated, or silver gives an modern appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of accurate forming and adapting to precise needs,
- Wide application in modern technologies – they are utilized in magnetic memories, electric drive systems, advanced medical instruments, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of making threads in the magnet and complex shapes - preferred is a housing - magnetic holder.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- using a base made of high-permeability steel, functioning as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at room temperature
Lifting capacity in practice – influencing factors
- Distance – the presence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Plate material – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Electronic hazard
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
GPS and phone interference
An intense magnetic field disrupts the operation of compasses in phones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
Conscious usage
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Flammability
Powder created during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Hand protection
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Danger to the youngest
Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Permanent damage
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Magnet fragility
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Sensitization to coating
Some people experience a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause dermatitis. We suggest wear safety gloves.
Medical interference
Patients with a heart stimulator must keep an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.
