Advantages and disadvantages of neodymium magnets.
Pros
- They do not lose power, even over approximately ten years – the decrease in lifting capacity is only ~1% (based on measurements),
- They have excellent resistance to magnetism drop as a result of external fields,
- A magnet with a shiny nickel surface has an effective appearance,
- Magnets are distinguished by very high magnetic induction on the outer layer,
- 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 custom forming as well as modifying to atypical needs,
- Universal use in electronics industry – they serve a role in hard drives, drive modules, medical devices, as well as technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of mild steel, effectively closing the magnetic flux
- with a thickness of at least 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- under vertical force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Clearance – the presence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
H&S for magnets
Swallowing risk
Strictly store magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are fatal.
Warning for allergy sufferers
Studies show that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select coated magnets.
Serious injuries
Pinching hazard: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Operating temperature
Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Safe operation
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Eye protection
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
Health Danger
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Threat to navigation
A powerful magnetic field negatively affects the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Keep away from computers
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Mechanical processing
Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
