Pros as well as cons of neodymium magnets.
Strengths
- Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic finish of silver, the element gains visual value,
- Neodymium magnets generate maximum magnetic induction on a small surface, which allows for strong attraction,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to the potential of accurate forming and adaptation to specialized needs, magnetic components can be produced in a broad palette of forms and dimensions, which increases their versatility,
- Key role in modern industrial fields – they serve a role in HDD drives, electric drive systems, medical equipment, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Highest magnetic holding force – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Distance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Steel thickness – too thin steel does not close the flux, causing part of the flux to be lost to the other side.
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Operating temperature
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Mechanical processing
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Electronic hazard
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Crushing risk
Large magnets can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Allergic reactions
Some people experience a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to a rash. We strongly advise wear safety gloves.
Beware of splinters
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Danger to pacemakers
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Handling rules
Use magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their power.
Keep away from electronics
A strong magnetic field negatively affects the operation of compasses in phones and navigation systems. Do not bring magnets close to a device to prevent damaging the sensors.
No play value
Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
