Horseshoe Ferrite Magnets also called ceramic horseshoe magnets or U-shape ferrite magnets, are widely used in teaching and playing. also known as ceramic educational magnets, are offered in a wide range of sizes, dimensions, shapes and colors.
We usually paint Ferrite horseshoe educational magnet in no color, red-green or red-blue, or we combine them with other material such as metal and plastic. Meantime, these products comply with the international safety standards.
Educational U-shape magnet is safe to children’s health. We manufacture educational magnets based on customers’ requirements. Computer, science, biological engineering, medical apparatus and instruments, instruments and meters.
