Magnetic Field Demonstrator – Set of 4 Plates for Clean, Clear Field Line Visualisation

This Magnetic Field Demonstrator (set of 4 plates) offers a clean, mess‑free way to reveal magnetic field lines in one, two, or three dimensions. Designed as a practical alternative to loose iron filings, these plates clearly show magnetic field patterns without the usual hassle of cleaning filings off magnets—a common challenge in classroom demonstrations.

The plates provide sharp, detailed visualisation of magnetic field lines when used with external magnets (sold separately). For best performance, Alnico magnets—such as codes 0337 or 2287—are recommended due to their strong and consistent magnetic fields.

Key Features

• Set of 4 magnetic field demonstration plates
• Provides clear, mess‑free field line patterns
• Ideal replacement for loose iron filings
• Demonstrates magnetic fields in 1D, 2D, and 3D
• Works with a wide range of classroom magnets
• Recommended magnets: Alnico types (e.g., codes 0337 or 2287)
• Durable and easy to clean—perfect for frequent school use

Ideal for School Science Lessons

This magnetic field demonstrator is perfect for KS3–KS4 physics lessons on magnetism and electromagnetism. Students can:

• Observe magnetic field lines around bar magnets, horseshoe magnets, and paired magnets
• Compare field shapes and strengths with different magnet types
• Explore north–south polarity, repulsion, and attraction
• Visualise fields in three dimensions without the mess of iron filings

The clean, reusable design makes it an essential resource for demonstrating magnetic concepts clearly, efficiently, and safely in the classroom.
