Pros and cons of neodymium magnets.
Pros
- They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
- They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
- A magnet with a metallic silver surface has better aesthetics,
- Magnets have excellent magnetic induction on the outer layer,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of individual modeling as well as optimizing to individual applications,
- Universal use in modern technologies – they are utilized in computer drives, brushless drives, precision medical tools, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- 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.
- When exposed to high temperature, neodymium magnets experience a drop in power. 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 corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- under conditions of no distance (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- in stable room temperature
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Magnetic media
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Risk of cracking
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into small pieces.
Life threat
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
This is not a toy
Neodymium magnets are not intended for children. Eating several magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates urgent medical intervention.
GPS Danger
A powerful magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Powerful field
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often quicker than you can move away.
Bodily injuries
Large magnets can smash fingers instantly. Never put your hand betwixt two strong magnets.
Do not overheat magnets
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Sensitization to coating
Certain individuals suffer from a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to dermatitis. We strongly advise use safety gloves.
Fire warning
Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
