Strengths and weaknesses of neodymium magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- Magnets very well resist against demagnetization caused by ambient magnetic noise,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
- Possibility of accurate machining as well as modifying to precise conditions,
- Key role in innovative solutions – they are utilized in computer drives, electromotive mechanisms, medical equipment, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these devices can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a sheet made of high-permeability steel, functioning as a magnetic yoke
- with a thickness no less than 10 mm
- with an ground contact surface
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Serious injuries
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Magnets are brittle
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Caution required
Use magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their force.
Do not give to children
Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
Safe distance
Do not bring magnets near a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Do not drill into magnets
Powder created during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Health Danger
Patients with a heart stimulator have to keep an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Phone sensors
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Skin irritation risks
Certain individuals experience a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching may cause skin redness. We recommend wear safety gloves.
