Technical Drawing
Areas of application
Neodymium rod magnets are made of the powerful neodymium-iron-boron (NdFeB) alloy and offer exceptionally high holding power compared to conventional ferrite or AlNiCo magnets. The combination of impressive magnetization capability and high flux density makes neodymium one of the strongest magnetic materials on the market. These properties provide optimal conditions for applications where high magnetic force is required in the smallest of spaces:
- Magnetic closures: Neodymium rod magnets can be used in jewelry clasps or bag closures because they provide a secure yet easy-to-release magnetic connection. Their slim, elongated shape allows for invisible installation in delicate clasps with optimal hold.
- Events and presentations: At trade fairs, exhibitions and presentations, neodymium rod magnets provide an easy way to securely and flexibly attach posters, signs and presentation materials. Their small size allows for unobtrusive attachment without damaging the material.
- Furniture making and interior design: Neodymium rod magnets are popular in furniture making for integrating concealed magnetic closures into cabinet doors and drawers. In interior design, they are used to attach panels and covers, where they are visually discreet yet extremely strong.
- Electrical engineering: Neodymium magnets play a central role in electrical engineering, particularly in the field of electromobility. They are installed in the electric motors of cars and bicycles, where they enable the rotation of the motors through the interaction of magnetic fields and electric current.
In addition, magnets are used in loudspeaker technology: In combination with a current-carrying coil, they generate sound waves in the loudspeaker by causing membranes to vibrate, thus making sounds audible. Their versatile application possibilities make magnets an indispensable component in modern technical systems.
