Pros and cons of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external field sources,
- Thanks to the smooth finish, the coating of nickel, gold, or silver-plated gives an visually attractive appearance,
- Magnetic induction on the surface of the magnet is extremely intense,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of detailed shaping and optimizing to complex needs,
- Huge importance in electronics industry – they serve a role in computer drives, drive modules, medical devices, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 as well as corrosion.
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using casing - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these products can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- with a thickness no less than 10 mm
- with an polished contact surface
- without the slightest air gap between the magnet and steel
- under axial force direction (90-degree angle)
- at standard ambient temperature
What influences lifting capacity in practice
- Distance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
Warnings
Heat sensitivity
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Serious injuries
Big blocks can smash fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.
Product not for children
Adult use only. Small elements pose a choking risk, causing serious injuries. Keep away from children and animals.
Magnets are brittle
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Medical implants
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Mechanical processing
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Keep away from electronics
An intense magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.
Handling rules
Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
Protect data
Equipment safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
