Strengths and weaknesses of neodymium magnets.
Strengths
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under external field action,
- Thanks to the smooth finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Considering the possibility of free molding and adaptation to unique needs, NdFeB magnets can be modeled in a broad palette of geometric configurations, which increases their versatility,
- Versatile presence in innovative solutions – they find application in magnetic memories, electric motors, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these devices can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic flux
- with a thickness minimum 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- at room temperature
Key elements affecting lifting force
- Gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, 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 decreases the lifting capacity.
Shattering risk
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Data carriers
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Combustion hazard
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
Thermal limits
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Threat to navigation
A strong magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.
Life threat
Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease handling magnets and use protective gear.
Do not give to children
Strictly keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.
Finger safety
Danger of trauma: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Caution required
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.
