Self Adhesive Round Ceramic Magnets, Pack of 50 Different Sizes

These small ceramic disc magnets provide a practical, ready-to-use solution for lightweight mounting and hands-on science activities. Arranged as a mixed set of fifty adhesive-backed ferrite magnets, they deliver reliable attachment for documents, photos, labels, and small craft items on standard steel surfaces.

• Mixed Dimension Set: Contains fifty pieces across five distinct diameters, ranging from compact 0.39-inch circles to larger 1.18-inch discs, all maintaining a consistent 0.12-inch profile.
• Pre-Attached Adhesive Backing: Each magnet includes a bonded adhesive layer that secures to project materials instantly without additional tape, glue, or drilling.
• Ceramic Ferrite Build: Constructed from stable ceramic material engineered to resist corrosion and retain consistent magnetic output during routine storage and use.
• Light-Duty Performance: Designed specifically for holding paper, photographs, classroom notices, and lightweight buttons rather than heavy tools or rigid frames.
• Surface Requirements: Delivers maximum attraction on clean, dry, smooth ferrous metal; effectiveness drops noticeably on thick paint, textured walls, aluminum, or standard stainless steel.
• STEM Demonstration Tool: The graduated sizing supports physics lessons on flux density, pole alignment, and comparative pull strength through side-by-side testing.
• Organized Profile: Uniform disc shapes with smoothed edges allow quick stacking and drawer storage while minimizing surface scratches during placement.
• Age Restriction Guideline: Smoothly finished edges support safe crafting handling, though the compact dimensions classify the magnets strictly for users aged fourteen and older.

This assorted kit simplifies both daily organization and structured learning by merging immediate adhesive application with scalable magnetic control. Educators and crafters can secure notes, construct simple motor models, or label storage solutions without damaging furniture or relying on temporary tapes, while the varied size distribution naturally demonstrates how diameter influences pulling force in tangible, visual ways.
