3D Magnetic Field Line Demonstrator,Physics Experimental Equipment

The 3D Magnetic Induction Line Demonstrator is a professional physics teaching aid tailored for middle school courses. It visualizes invisible magnetic field directions and induction lines, turning abstract electromagnetism theories into intuitive visible patterns to help students learn efficiently.Complete Product StructureAccessories List: Bar magnet, horseshoe magnet, 6 rectangular transparent magnetic induction plates, 1 crescent transparent induction plate, stable fixed bracketTransparent Design: Fully transparent panels offer unobstructed viewing of magnetic field distribution during classroom or lab demonstrations.Simple Operation Steps1. Shake the device repeatedly to scatter internal tiny iron filings evenly.2. Take out the movable semicircular plate, install the horseshoe magnet, then lightly tap the plate surface; iron filings will automatically arrange to show complete magnetic induction lines.3. For bar magnet experiments, replace the semicircular plate with the I-shaped plate to get precise demonstration effects.4. Easy to operate, fit for teacher class display and student hands-on experiment.Daily Maintenance Guidelines1. Keep away from external strong magnets to avoid affecting demonstration precision.2. Prevent collisions with hard items to avoid cracks or deformation of transparent panels.3. Do not touch transparent plates and magnets with organic solvents to extend service life.
