Pros and cons of neodymium magnets.
Strengths
- They have constant strength, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- Thanks to the elegant finish, the plating of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of exact forming as well as optimizing to complex conditions,
- Key role in advanced technology sectors – they are used in data components, electric drive systems, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Weaknesses
- Brittleness 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 raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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 start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of creating nuts in the magnet and complex shapes - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a base made of high-permeability steel, serving as a ideal flux conductor
- whose thickness is min. 10 mm
- characterized by smoothness
- with total lack of distance (without coatings)
- under axial force direction (90-degree angle)
- at standard ambient temperature
Determinants of lifting force in real conditions
- Clearance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Beware of splinters
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Compass and GPS
Remember: neodymium magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Safe distance
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Serious injuries
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Operating temperature
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.
Medical implants
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Handling rules
Be careful. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.
Choking Hazard
Product intended for adults. Small elements pose a choking risk, causing severe trauma. Store away from children and animals.
Skin irritation risks
Medical facts indicate that nickel (the usual finish) is a common allergen. If you have an allergy, prevent direct skin contact and select encased magnets.
