Magnetic Field Viewing Film – Instant Visualization of Magnetic Poles & Flux Patterns

• Core Design: Thin, flexible polymer sheet with a micro-encapsulated ferrofluid layer – one side is the viewing surface (olive-green/gold), the other is a protective black backing.
• Core Benefit: Instantly visualize magnetic pole distribution, flux patterns, and N/S pole orientation – no power, no calibration, no complex setup.
• Core Flexibility: Available in standard sheets, rolls, and custom shapes (discs, squares with holes) to fit any magnet size or shape (round, block, ring, custom).
• Core Durability: Reusable, scratch-resistant, and stable under normal conditions – ideal for repeated inspection and testing.

⭐ Key Features (Conversion-Driven Selling Points)

🔹 1. Instant, High-Contrast Magnetic Field Visualization

• Clear Pole Patterns: The film reacts instantly to magnetic fields, revealing distinct patterns for N/S poles (dark/light contrast) and magnetic flux lines.
• No Power Required: Passive visualization – just place the film over a magnet and see the field pattern immediately.
• High Sensitivity: Detects even weak magnetic fields (≥100 Gauss) – perfect for small neodymium magnets and precision components.
• Sharp Resolution: Fine-grained ferrofluid particles produce crisp, detailed patterns for accurate pole identification and defect detection.

🔹 2. Flexible, Reusable & Versatile Format

• Flexible Sheet Design: Thin, bendable film conforms to curved or irregular magnet surfaces (e.g., round magnets, ring magnets).
• Reusable: Wipe clean with a soft cloth and reuse indefinitely – no degradation with normal use.
• Multiple Formats:
  • Standard Sheets: 100×100mm, 200×200mm, A4 (210×297mm) – ready for immediate use.
  • Rolls: Custom-length rolls (1m/5m/10m) for large-scale inspection or continuous use.
  • Custom Shapes: Discs, squares with mounting holes, or cut-to-size shapes (e.g., 5-hole square for fixture mounting) – perfect for automated inspection setups.
• Protective Backing: Black reverse side protects the ferrofluid layer and enhances contrast for clearer viewing.
