Advantages and disadvantages of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly resist against demagnetization caused by ambient magnetic noise,
- By covering with a smooth layer of gold, the element gains an proper look,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of custom forming as well as adapting to complex conditions,
- Key role in innovative solutions – they serve a role in computer drives, electric motors, advanced medical instruments, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- using a base made of low-carbon steel, functioning as a circuit closing element
- with a thickness no less than 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- under axial force vector (90-degree angle)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin steel does not close the flux, causing part of the power to be lost into the air.
- Plate material – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Protective goggles
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Safe operation
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Magnetic interference
GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Allergy Warning
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for coated magnets.
Maximum temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Crushing force
Danger of trauma: The attraction force is so great that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Do not give to children
Adult use only. Small elements can be swallowed, causing intestinal necrosis. Keep away from children and animals.
Safe distance
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Warning for heart patients
Patients with a pacemaker must keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Fire risk
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
