12mm x 3mm Ferrite Disc Magnet (Dia 12mm, Height 3mm)

12mm × 3mm Ferrite Disc Magnet (Dia 12mm, Height 3mm)

This ferrite disc magnet is made from sintered strontium ferrite (ceramic), one of the most widely used and cost-effective permanent magnet materials available. With a diameter of 12mm and a height of 3mm, it offers a generously wide surface area that delivers a strong and evenly distributed magnetic hold for everyday applications. The larger 12mm diameter makes it a popular choice where a wider magnetic footprint is needed without adding extra height. Ferrite magnets are naturally resistant to corrosion and demagnetisation, making them a practical long-lasting choice for both indoor and outdoor use without any protective coating needed.
