30x20x8mm Ferrite Bar Magnet (Length 30mm, Width 20mm, Height 8mm)

30mm × 20mm × 8mm Ferrite Bar Magnet (Length 30mm, Width 20mm, Height 8mm)

This ferrite bar magnet is made from sintered strontium ferrite (ceramic), one of the most widely used and cost-effective permanent magnet materials available. With a length of 30mm, width of 20mm, and a height of 8mm, this is a large and robust rectangular bar magnet that combines a wide surface area with a greater thickness, delivering a noticeably stronger pull force and deeper magnetic field penetration compared to thinner variants of the same dimensions. The generous 30mm length and 20mm width provide a broad magnetic footprint while the solid 8mm height makes this one of the more powerful ferrite bar magnets in its class, well suited for heavier duty applications where both reach and holding strength are essential. 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.

Key Features

• Large 30mm × 20mm surface area delivers a broad magnetic footprint for strong and stable contact
