Pros and cons of rare earth magnets.
Benefits
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They feature excellent resistance to magnetic field loss due to opposing magnetic fields,
- A magnet with a metallic gold surface has an effective appearance,
- Magnetic induction on the working part of the magnet remains very high,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise shaping and adjusting to atypical needs,
- Universal use in future technologies – they find application in HDD drives, electromotive mechanisms, advanced medical instruments, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in force. 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with an polished contact surface
- with total lack of distance (without coatings)
- under perpendicular application of breakaway force (90-degree angle)
- at standard ambient temperature
What influences lifting capacity in practice
- Air gap (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Material type – the best choice is high-permeability steel. Cast iron may attract less.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Safe handling of neodymium magnets
Allergic reactions
Certain individuals have a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to an allergic reaction. We recommend wear protective gloves.
Crushing force
Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Electronic hazard
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Health Danger
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Handling guide
Use magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their power.
Do not give to children
Neodymium magnets are not toys. Swallowing several magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Compass and GPS
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Eye protection
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
