Pros as well as cons of neodymium magnets.
Benefits
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are distinguished by exceptionally resistant to demagnetization caused by external magnetic fields,
- Thanks to the glossy finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the surface of the magnet is extremely intense,
- 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...
- Due to the ability of free molding and adaptation to specialized projects, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which increases their versatility,
- Key role in electronics industry – they are commonly used in computer drives, electromotive mechanisms, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power 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 rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- using a base made of high-permeability steel, acting as a circuit closing element
- with a cross-section minimum 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Air gap (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Electronic devices
Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Do not overheat magnets
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Bone fractures
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Phone sensors
GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Fire risk
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Warning for heart patients
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Danger to the youngest
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates immediate surgery.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease handling magnets and use protective gear.
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Magnet fragility
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.
