40x20x6mm Ferrite Bar Magnet (Length 40mm, Width 20mm, Height 6mm)

40mm × 20mm × 6mm Ferrite Bar Magnet (Length 40mm, 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 40mm, width of 20mm, and a height of 6mm, this is a large elongated rectangular bar magnet that delivers a strong and evenly distributed magnetic hold across a generous surface area. The extended 40mm length combined with the wide 20mm width provides one of the broadest magnetic footprints in the standard ferrite bar magnet range, while the 6mm height adds solid pull force and field depth. This makes it an excellent choice for applications where maximum surface coverage and a reliable magnetic hold over a wide area 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.
