Magnetic Induction

Other products

Unlike safety pins or pins, magnetic fastening leaves no marks or holes on the material. This ensures elegance and wearing comfort, without the risk of pricking yourself or ruining clothes. It's a standard solution at conferences, trade fairs, and in companies caring about image.
The set includes a strip with magnets (put under clothes) and a steel plate with tape (on the outside). You stick your badge on the plate, and the magnet holds it through the clothing material. Magnets are hidden in an aesthetic plastic housing that does not irritate the skin.
Attraction force is sufficient to hold the badge even on winter clothing. A larger number of magnetic points prevents the badge from twisting.
There is a risk of disrupting pacemaker operation by a strong magnetic field, so we advise against this solution for people with implants. For other people, magnets are completely safe and indifferent to health.
Yes, we are a direct importer and fulfill large wholesale orders. Contact us to receive an individual B2B offer tailored to your company's needs.

Pros as well as cons of Nd2Fe14B magnets.

Advantages

Besides their tremendous field intensity, neodymium magnets offer the following advantages:
  • They do not lose power, even over approximately 10 years – the drop in strength is only ~1% (based on measurements),
  • Neodymium magnets remain highly resistant to magnetic field loss caused by external magnetic fields,
  • The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnets have impressive magnetic induction on the outer side,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
  • Possibility of precise creating and optimizing to individual needs,
  • Versatile presence in modern industrial fields – they find application in data components, electric motors, medical equipment, and industrial machines.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Drawbacks and weaknesses of neodymium magnets: tips and applications.
  • At very strong impacts they can crack, therefore we advise placing them in special holders. 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 and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • We recommend cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these products are able to complicate diagnosis medical in case of swallowing.
  • With mass production the cost of neodymium magnets is a challenge,

Lifting parameters

Best holding force of the magnet in ideal parameterswhat affects it?

Information about lifting capacity is the result of a measurement for ideal contact conditions, taking into account:
  • on a plate made of structural steel, effectively closing the magnetic field
  • with a cross-section minimum 10 mm
  • with a plane free of scratches
  • with direct contact (no coatings)
  • during pulling in a direction perpendicular to the mounting surface
  • in stable room temperature

Impact of factors on magnetic holding capacity in practice

Real force is influenced by specific conditions, mainly (from priority):
  • Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Base massiveness – too thin plate does not accept the full field, causing part of the power to be lost to the other side.
  • Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
  • Base smoothness – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings
Fire warning

Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

This is not a toy

Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.

Powerful field

Handle with care. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can react.

Hand protection

Large magnets can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.

Magnets are brittle

Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets leads to them shattering into small pieces.

Thermal limits

Keep cool. Neodymium magnets are susceptible to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).

Phone sensors

Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and GPS.

Health Danger

Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to work with the magnets.

Electronic hazard

Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.

Warning! More info about hazards in the article: Safety of working with magnets.
