Pros and cons of rare earth magnets.
Advantages
- Their power is maintained, and after around ten years it drops only by ~1% (according to research),
- Magnets effectively defend themselves against demagnetization caused by external fields,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the working part of the magnet turns out to be extremely intense,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Due to the ability of free forming and customization to unique needs, NdFeB magnets can be manufactured in a broad palette of geometric configurations, which expands the range of possible applications,
- Universal use in high-tech industry – they serve a role in magnetic memories, brushless drives, advanced medical instruments, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their 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 very resistant to heat
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using cover - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Highest magnetic holding force – what it depends on?
- with the contact of a yoke made of special test steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- 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
What influences lifting capacity in practice
- Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
Health Danger
Patients with a ICD have to maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Thermal limits
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Physical harm
Danger of trauma: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Magnetic media
Intense magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
Handling guide
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Magnetic interference
An intense magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.
Fire risk
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Nickel coating and allergies
Studies show that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or choose versions in plastic housing.
Material brittleness
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
