Pros and cons of rare earth magnets.
Strengths
- They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by external magnetic fields,
- By applying a lustrous coating of nickel, the element gains an modern look,
- Magnetic induction on the top side of the magnet turns out to be extremely intense,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of custom creating and adjusting to specific conditions,
- Versatile presence in modern industrial fields – they find application in computer drives, electric motors, precision medical tools, and modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complex shapes - recommended is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these devices are able to disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Key elements affecting lifting force
- Clearance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin plate does not close the flux, causing part of the power to be lost to the other side.
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Precautions when working with NdFeB magnets
No play value
Strictly keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.
Magnetic media
Do not bring magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.
Warning for heart patients
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Shattering risk
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Power loss in heat
Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and strength.
Do not underestimate power
Handle with care. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.
Nickel allergy
Some people suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling can result in an allergic reaction. We recommend use protective gloves.
GPS and phone interference
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.
Do not drill into magnets
Dust generated during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Bodily injuries
Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
