Magnaprobe 3D Magnetic Field Indicator – Mark II

The Magnaprobe Mark II 3D Magnetic Field Indicator is a compact and highly effective teaching tool designed to demonstrate the three‑dimensional nature of magnetic fields. It features a small bar magnet fully suspended within a precision gimbal mounting, allowing the magnet to freely align itself with surrounding magnetic fields.

Unlike simple compasses that only show direction in a single plane, the Magnaprobe responds in all three dimensions, making invisible magnetic fields visible and easy to understand. The Mark II version is specifically designed to operate reliably in stronger magnetic fields, making it ideal for common school laboratory investigations using bar magnets, horseshoe magnets, and electromagnets.

Key Features

• 3D magnetic field indicator for visualising magnetic fields
• Small bar magnet fully suspended in a gimbal mount
• Clearly shows the direction and shape of magnetic fields
• Responds in three dimensions, not just one plane
• Mark II model designed for stronger magnetic fields
• Ideal for school laboratory investigations
• Compact, robust, and easy to handle

Ideal for School Science Lessons

The Magnaprobe Mark II is ideally suited to KS3, GCSE, and A‑Level physics lessons, helping students explore and understand magnetic fields through hands‑on observation. It is particularly valuable for developing conceptual understanding beyond flat diagrams.

• Demonstrating the shape and direction of magnetic fields
• Investigating fields around bar magnets and electromagnets
• Exploring field strength and orientation
• Supporting discussion of 3D magnetic field models
• Enhancing practical investigations without iron filings

Clear, engaging, and highly visual, the Magnaprobe 3D Magnetic Field Indicator is an excellent resource for bringing abstract physics concepts to life and supporting safe, effective, and meaningful hands‑on learning about magnetism in the classroom.
