Advantages and disadvantages of rare earth magnets.
Pros
- They retain attractive force for nearly 10 years – the loss is just ~1% (based on simulations),
- They are resistant to demagnetization induced by external field influence,
- By using a smooth layer of silver, the element gains an modern look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of detailed machining as well as optimizing to concrete conditions,
- Versatile presence in high-tech industry – they are commonly used in computer drives, motor assemblies, diagnostic systems, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices can complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- with an ideally smooth contact surface
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at temperature room level
Impact of factors on magnetic holding capacity in practice
- Air gap (betwixt the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Warnings
Danger to pacemakers
For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Impact on smartphones
A powerful magnetic field negatively affects the functioning of compasses in phones and navigation systems. Do not bring magnets near a device to prevent damaging the sensors.
Hand protection
Large magnets can break fingers instantly. Under no circumstances put your hand between two attracting surfaces.
This is not a toy
Strictly store magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are very dangerous.
Caution required
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Sensitization to coating
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact or select coated magnets.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Beware of splinters
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
Mechanical processing
Dust produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Magnetic media
Intense magnetic fields can destroy records on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
