Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain attractive force for nearly 10 years – the loss is just ~1% (based on simulations),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- By covering with a smooth layer of gold, the element acquires an professional look,
- They feature high magnetic induction at the operating surface, which increases their power,
- 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 creating and modifying to defined applications,
- Key role in modern industrial fields – they are commonly used in HDD drives, electromotive mechanisms, medical devices, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium 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 very resistant to heat
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complicated shapes in magnets, we recommend using cover - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a plate made of mild steel, serving as a circuit closing element
- whose thickness equals approx. 10 mm
- with an polished touching surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Distance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Danger to pacemakers
People with a ICD should keep an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.
Safe operation
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Pinching danger
Large magnets can break fingers instantly. Do not put your hand betwixt two strong magnets.
Compass and GPS
Note: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your phone, device, and GPS.
Keep away from children
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Store away from children and animals.
Combustion hazard
Dust generated during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Warning for allergy sufferers
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.
Fragile material
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
Do not overheat magnets
Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Electronic hazard
Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
