Advantages and disadvantages of rare earth magnets.
Benefits
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by magnetic disturbances,
- In other words, due to the glossy surface of silver, the element gains a professional look,
- Magnets are distinguished by excellent magnetic induction on the outer side,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of individual creating and adapting to precise conditions,
- Wide application in advanced technology sectors – they are used in HDD drives, electric drive systems, medical equipment, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in producing nuts and complex forms in magnets, we propose using casing - magnetic mount.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of mild steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- with direct contact (no paint)
- during detachment in a direction vertical to the plane
- at temperature room level
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Safe operation
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Warning for heart patients
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Product not for children
Neodymium magnets are not toys. Eating several magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
Fire risk
Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Keep away from electronics
Remember: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Finger safety
Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Protect data
Do not bring magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Do not overheat magnets
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Warning for allergy sufferers
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands and choose coated magnets.
Risk of cracking
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.
