Advantages as well as disadvantages of rare earth magnets.
Strengths
- Their strength is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
- Magnetic induction on the top side of the magnet remains extremely intense,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of accurate shaping as well as adapting to defined conditions,
- Universal use in modern industrial fields – they are utilized in computer drives, electromotive mechanisms, diagnostic systems, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited possibility of making nuts in the magnet and complicated forms - recommended is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction vertical to the mounting surface
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be escaped into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Warnings
Heat sensitivity
Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Implant safety
Individuals with a heart stimulator have to maintain an safe separation from magnets. The magnetism can stop the operation of the life-saving device.
Phone sensors
A powerful magnetic field interferes with the operation of magnetometers in phones and navigation systems. Keep magnets near a smartphone to avoid damaging the sensors.
Data carriers
Do not bring magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Material brittleness
Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Combustion hazard
Dust produced during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Respect the power
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.
This is not a toy
These products are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Physical harm
Pinching hazard: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Metal Allergy
Studies show that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid direct skin contact and choose coated magnets.
