Strengths and weaknesses of neodymium magnets.
Benefits
- They retain magnetic properties for almost ten years – the loss is just ~1% (in theory),
- Magnets very well resist against demagnetization caused by ambient magnetic noise,
- A magnet with a shiny nickel surface looks better,
- Magnets exhibit huge magnetic induction on the outer side,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of exact shaping as well as adapting to defined applications,
- Significant place in innovative solutions – they find application in magnetic memories, motor assemblies, medical devices, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 immune to moisture, when using outdoors
- We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a sheet made of mild steel, functioning as a circuit closing element
- with a cross-section no less than 10 mm
- with a surface perfectly flat
- under conditions of ideal adhesion (surface-to-surface)
- under axial application of breakaway force (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be wasted into the air.
- Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Do not give to children
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from kids and pets.
Impact on smartphones
A strong magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Heat sensitivity
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Physical harm
Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Nickel allergy
Some people suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling might lead to an allergic reaction. We suggest use safety gloves.
Magnet fragility
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Danger to pacemakers
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Mechanical processing
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Handling guide
Handle with care. Neodymium magnets act from a long distance and connect with huge force, often faster than you can move away.
Electronic devices
Intense magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
