Advantages and disadvantages of rare earth magnets.
Strengths
- They retain magnetic properties for around ten years – the loss is just ~1% (in theory),
- Neodymium magnets are extremely resistant to demagnetization caused by magnetic disturbances,
- By using a lustrous coating of gold, the element presents an nice look,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to versatility in constructing and the capacity to modify to individual projects,
- Significant place in electronics industry – they are commonly used in magnetic memories, electromotive mechanisms, medical devices, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with a surface free of scratches
- without any insulating layer between the magnet and steel
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Air gap (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be wasted to the other side.
- Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Machining danger
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Magnetic interference
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.
Heat sensitivity
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.
Handling rules
Use magnets with awareness. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Cards and drives
Very strong magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Warning for allergy sufferers
Some people have a sensitization to nickel, which is the common plating for NdFeB magnets. Prolonged contact can result in dermatitis. It is best to wear protective gloves.
Choking Hazard
Strictly store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.
Implant safety
Patients with a ICD must maintain an large gap from magnets. The magnetic field can disrupt the functioning of the implant.
Pinching danger
Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
