The round ferrite (ceramic) magnet measuring 30x3mm is a highly durable permanent magnet manufactured primarily from iron oxide and strontium carbonate. Providing a strong pull force of 700 grams due to its large diameter, it excels in its absolute resistance to rust and harsh weather conditions. It represents the most reliable and cost-effective choice for outdoor applications, large DIY crafts, and school experiments. Sold individually.

Large Contact Surface and Strong Durability

The 30x3mm ferrite disc is a classic, proven magnetic solution for everyday tasks requiring a large contact surface. As a ceramic magnet, it offers superior resistance to corrosion and weather elements compared to neodymium, delivering a reliable and steady pull force of 700 grams.

Key Features

  • Absolute Rust Immunity: Its natural chemical composition makes it 100% waterproof, allowing for permanent outdoor use (gardens, balconies, signs) without needing any protective coating.
  • Strong Pull (700g): The expanded 30mm diameter greatly increases the contact area, offering a secure hold for larger or heavier objects.
  • Excellent Application: The top choice for larger souvenirs, fridge decorations, school builds, industrial signage, and hobbies.

Frequently Asked Questions (FAQ)

Are these magnets suitable for outdoor use?
Yes, absolutely. Unlike sensitive neodymium, ferrite magnets withstand the elements perfectly. They will not oxidize or rust, even if they are continuously exposed to rain or sun.

What weight can this magnet (30x3mm) hold?
Its pull force is estimated at 700 grams under ideal contact conditions. Although the magnetic field of ferrite is milder than neodymium, its large diameter helps it securely hold cardboard, small tools, or be glued to the back of large clay and wooden crafts.

Safety Note (Ceramic Material): Ferrite magnets have a ceramic structure. This makes them extremely hard but also brittle (they behave like glass or porcelain). They may chip or shatter if dropped on a hard floor or if allowed to forcefully collide with each other.
