Other proposals
Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They have excellent resistance to magnetic field loss due to opposing magnetic fields,
- In other words, due to the glossy finish of nickel, the element gains a professional look,
- Neodymium magnets create maximum magnetic induction on a their surface, which allows for strong attraction,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual forming as well as adjusting to complex conditions,
- Wide application in advanced technology sectors – they are used in HDD drives, drive modules, medical equipment, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems
Cons
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these devices can disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Highest magnetic holding force – what contributes to it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- with a cross-section of at least 10 mm
- with a plane perfectly flat
- without any air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate reduces the holding force.
Precision electronics
An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.
Powerful field
Use magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and respect their force.
Eye protection
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Serious injuries
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Do not overheat magnets
Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Medical interference
Individuals with a heart stimulator should keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.
Adults only
NdFeB magnets are not intended for children. Eating several magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.
Nickel coating and allergies
Studies show that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact and choose coated magnets.
Fire warning
Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Protect data
Device Safety: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
