Advantages and disadvantages of neodymium magnets.
Strengths
- Their strength remains stable, and after around ten years it decreases only by ~1% (theoretically),
- They are extremely resistant to demagnetization induced by external disturbances,
- By using a shiny coating of silver, the element has an proper look,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of individual creating as well as adjusting to defined requirements,
- Key role in electronics industry – they find application in hard drives, electric motors, advanced medical instruments, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Electronic devices
Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Heat warning
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Metal Allergy
A percentage of the population experience a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to skin redness. It is best to use protective gloves.
Hand protection
Pinching hazard: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Handling guide
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Pacemakers
Patients with a heart stimulator have to maintain an large gap from magnets. The magnetism can stop the operation of the life-saving device.
Machining danger
Machining of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Material brittleness
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Phone sensors
A powerful magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Adults only
Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.
