Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even during approximately ten years – the drop in lifting capacity is only ~1% (theoretically),
- They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
- A magnet with a shiny nickel surface looks better,
- Magnetic induction on the working layer of the magnet is impressive,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in designing and the ability to modify to individual projects,
- Key role in advanced technology sectors – they are utilized in magnetic memories, electric motors, diagnostic systems, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
- Possible danger 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 components of these devices can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- whose thickness reaches at least 10 mm
- with a surface free of scratches
- without any insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- at temperature room level
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic permeability and lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
GPS Danger
Be aware: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, device, and navigation systems.
Hand protection
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, destroying everything in their path. Be careful!
No play value
Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
Dust explosion hazard
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop handling magnets and wear gloves.
Warning for heart patients
Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Electronic devices
Powerful magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Fragile material
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Conscious usage
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Maximum temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
