Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even over nearly ten years – the decrease in lifting capacity is only ~1% (theoretically),
- They possess excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- A magnet with a smooth silver surface looks better,
- Magnets exhibit very high magnetic induction on the surface,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in shaping and the capacity to modify to unusual requirements,
- Universal use in advanced technology sectors – they find application in HDD drives, electric motors, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in small systems
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We suggest casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- using a base made of mild steel, functioning as a circuit closing element
- with a cross-section no less than 10 mm
- with an ideally smooth contact surface
- under conditions of gap-free contact (surface-to-surface)
- 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 plate), since even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot 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 the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Warnings
Skin irritation risks
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or opt for encased magnets.
Warning for heart patients
Patients with a heart stimulator have to keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Combustion hazard
Dust created during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Conscious usage
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often faster than you can react.
Adults only
Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep out of reach of children and animals.
Threat to navigation
An intense magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a device to prevent damaging the sensors.
Protect data
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Thermal limits
Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and strength.
Protective goggles
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Bodily injuries
Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
