Pros as well as cons of NdFeB magnets.
Strengths
- They retain attractive force for nearly 10 years – the drop is just ~1% (according to analyses),
- Magnets very well resist against loss of magnetization caused by ambient magnetic noise,
- A magnet with a smooth silver surface has better aesthetics,
- Magnetic induction on the working part of the magnet is impressive,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in forming and the ability to customize to complex applications,
- Universal use in modern industrial fields – they are commonly used in computer drives, electric drive systems, medical devices, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields 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 strength 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making nuts in the magnet and complicated forms - recommended is cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these devices can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by even structure
- without the slightest clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Operating temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Dust explosion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.
Crushing force
Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Pacemakers
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Impact on smartphones
A strong magnetic field disrupts the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.
Electronic devices
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Adults only
Adult use only. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
Nickel allergy
Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or select versions in plastic housing.
Do not underestimate power
Use magnets consciously. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their force.
