Advantages and disadvantages of neodymium magnets.
Advantages
- Their power is durable, and after approximately ten years it decreases only by ~1% (according to research),
- They have excellent resistance to magnetism drop due to external magnetic sources,
- Thanks to the metallic finish, the surface of nickel, gold, or silver-plated gives an elegant appearance,
- Magnetic induction on the working layer of the magnet remains very high,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in shaping and the ability to customize to complex applications,
- Universal use in innovative solutions – they are utilized in computer drives, electromotive mechanisms, medical devices, as well as complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited ability of making threads in the magnet and complex forms - recommended is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small components of these devices can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- using a sheet made of mild steel, acting as a circuit closing element
- whose thickness reaches at least 10 mm
- with a surface cleaned and smooth
- without the slightest clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at temperature room level
Determinants of lifting force in real conditions
- Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be lost into the air.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate reduces the holding force.
Warnings
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets leads to them breaking into small pieces.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness occurs, immediately stop handling magnets and wear gloves.
Immense force
Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their force.
Danger to pacemakers
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
GPS Danger
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Pinching danger
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Keep away from computers
Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Power loss in heat
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Product not for children
Only for adults. Small elements can be swallowed, leading to severe trauma. Store away from children and animals.
Machining danger
Dust created during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
