Advantages and disadvantages of rare earth magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a smooth silver surface looks better,
- They show high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to versatility in forming and the ability to customize to unusual requirements,
- Universal use in high-tech industry – they are used in mass storage devices, electric drive systems, advanced medical instruments, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power 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 those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in producing threads and complicated forms in magnets, we recommend using a housing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these devices are able to complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of structural steel, optimally conducting the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction vertical to the plane
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the load capacity.
H&S for magnets
Medical interference
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Caution required
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
No play value
Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.
Safe distance
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Material brittleness
Neodymium magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets will cause them shattering into shards.
Dust explosion hazard
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Power loss in heat
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Pinching danger
Risk of injury: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
GPS and phone interference
Be aware: neodymium magnets produce a field that interferes with precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
