36mm x 18mm x 8mm Ferrite Ring Magnet (Outer Dia 36mm, Inner Dia 18, Height 8mm)

36mm × 18mm × 8mm Ferrite Ring Magnet (Outer Dia 36mm, Inner Dia 18mm, Height 8mm)

This ferrite ring magnet is made from sintered strontium ferrite (ceramic), one of the most widely used and cost-effective permanent magnet materials available. With an outer diameter of 36mm, inner diameter of 18mm, and a height of 8mm, this is a large and sturdy ring magnet that delivers a strong and reliable magnetic hold across a wide surface area. The generous 8mm height combined with the wide 36mm outer diameter makes this one of the more powerful ferrite ring magnets, well suited for heavier duty mechanical and industrial applications. The central hole with an 18mm inner diameter allows rods, shafts, fasteners, or cables to pass through with ease, adding to its versatility across a wide range of uses. 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.
