Pros and cons of rare earth magnets.
Pros
- They retain magnetic properties for nearly 10 years – the drop is just ~1% (according to analyses),
- They maintain their magnetic properties even under external field action,
- Thanks to the shiny finish, the surface of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in constructing and the capacity to adapt to complex applications,
- Huge importance in innovative solutions – they are utilized in hard drives, electric motors, advanced medical instruments, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complex shapes - recommended is cover - magnet mounting.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- with an ideally smooth contact surface
- with zero gap (without paint)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Practical lifting capacity: influencing factors
- Distance – the presence of any layer (rust, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
This is not a toy
Absolutely store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
Handling guide
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Physical harm
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Life threat
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Permanent damage
Avoid heat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Impact on smartphones
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
Electronic hazard
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Flammability
Dust generated during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Allergic reactions
Some people experience a contact allergy to nickel, which is the standard coating for NdFeB magnets. Extended handling may cause a rash. We strongly advise use safety gloves.
