40x25x10mm Ferrite Bar Magnet (Length 40mm, Width 25mm, Height 10mm)

40mm × 25mm × 10mm Ferrite Bar Magnet (Length 40mm, Width 25mm, Height 10mm)

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 40mm, width of 25mm, and a height of 10mm, this is a large and heavy duty rectangular bar magnet that combines an expansive surface area with a substantial height, delivering one of the strongest pull forces and deepest magnetic field penetrations in the standard ferrite bar magnet range. The extended 40mm length and wide 25mm width provide a broad magnetic footprint while the solid 10mm height adds considerable holding strength, making this magnet an excellent choice for demanding applications where both surface coverage and powerful magnetic performance are required. 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.
