Ferrite bar magnets
Ferrite bar magnets, composed of iron oxide mixed with strontium or barium carbonate, are a type of ceramic magnet known for their durability and magnetic stability. These magnets are relatively inexpensive to produce and offer good resistance to demagnetization and corrosion, which makes them suitable for a variety of industrial applications.
Their bar shape provides a straightforward, uniform magnetic field, ideal for educational purposes to demonstrate magnetic principles, as well as for magnetic assemblies where extensive magnetic reach is necessary. Ferrite bar magnets are typically manufactured through a sintering process, where powdered materials are pressed and fired at high temperatures to achieve their final form.
Commonly used in sensors, speakers, and holding devices, ferrite bar magnets are appreciated for their ability to perform consistently under diverse environmental conditions without significant degradation. Their robustness, coupled with low cost, makes them particularly effective for use in outdoor applications and cost-sensitive projects where high magnetic force is not a critical requirement.
