Strengths and weaknesses of rare earth magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets remain extremely resistant to magnetic field loss caused by external magnetic fields,
- By covering with a shiny coating of nickel, the element presents an modern look,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Considering the option of free shaping and adaptation to unique needs, NdFeB magnets can be manufactured in a broad palette of forms and dimensions, which makes them more universal,
- Significant place in modern industrial fields – they are utilized in mass storage devices, brushless drives, advanced medical instruments, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these devices can complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of high-permeability steel, serving as a circuit closing element
- with a thickness of at least 10 mm
- with an ground touching surface
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Gap (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Direction of force – highest force is obtained 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).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
H&S for magnets
Keep away from electronics
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Handling guide
Handle magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and respect their power.
Demagnetization risk
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Nickel allergy
A percentage of the population experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling may cause a rash. It is best to wear safety gloves.
Magnetic media
Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Magnets are brittle
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Fire warning
Machining of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
ICD Warning
Patients with a pacemaker must maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Keep away from children
Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are very dangerous.
Finger safety
Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
