Product Description The 70x15mm Ring Magnet is a high-durability ferrite (ceramic) magnet designed for industrial, educational, and heavy-duty DIY applications. Featuring a standard 70mm outer diameter and a substantial 15mm thickness, this magnet provides a deep magnetic field. Ferrite magnets are highly resistant to corrosion and demagnetization, making them suitable for use in harsh environments or high-temperature settings without the need for specialized protective coatings.

Key Features

  • Corrosion Resistant: Naturally rust-proof; requires no plating, making it ideal for outdoor or underwater projects.

  • Thermal Stability: Can withstand temperatures up to 250°C without losing magnetic strength.

  • Cost-Effective Power: Provides a steady, reliable magnetic pull at a much lower cost than Neodymium alternatives.

  • Versatile Geometry: The central hole allows for easy mechanical mounting using bolts, screws, or threaded rods.

  • Non-Conductive: Being a ceramic material, it acts as an electrical insulator.

Technical Details

  • Material Grade: Y30 / C5 (Standard Industrial Grade).

  • Pull Force: Significant vertical pull (depending on the thickness of the steel surface).

  • Fragility: Like all ceramic magnets, it is brittle; avoid high-impact collisions with other magnets or hard surfaces.

Prototyping and Engineering Tips from Robogears

  • Magnetic Separator: Use this ring magnet to build a DIY metal debris collector. By mounting it on a handle, you can quickly clear a workshop floor of screws and metal shavings.

  • Generator Basics: This size is perfect for educational demonstrations of Faraday’s Law. Pass a coil of wire through the center or move the magnet over a coil to generate a measurable electrical current.

  • Mounting Tip: Since ceramic magnets are brittle, do not over-tighten bolts through the center hole. Use a rubber washer to distribute pressure and prevent the magnet from cracking.

  • Loudspeaker Repair: These magnets are commonly used in the motor assemblies of large subwoofers or midrange drivers.

Package Includes

  • 1 x 70x15mm Ferrite Ring Magnet
