30x20x6mm Ferrite Bar Magnet (Length 30mm, Width 20mm, Height 6mm)

30mm × 20mm × 6mm Ferrite Bar Magnet (Length 30mm, Width 20mm, Height 6mm)

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 6mm, this is a large rectangular bar magnet that combines a wide surface area with a solid height, delivering a strong and evenly distributed magnetic hold well suited for heavier duty everyday and light industrial applications. The generous 30mm length and 20mm width provide a broad magnetic footprint while the 6mm height adds substantial pull force and field depth, making this one of the more capable ferrite bar magnets in its class. 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.
