About This

• Adopts precision coils and magnets with electromagnetic drive, regulating current to drive stable high-speed iron ball circulation and display electromagnetic acceleration principles intuitively.
• Premium bracket and guide rail build solid stable structure with smooth ball track, suitable for repeated classroom physics demos and long-term lab experiments.
• Single iron ball design avoids mutual interference; accurately adjust acceleration, deceleration and steering to clearly observe electromagnetic physical laws.
• 12–24V wide DC voltage input with standard 5.5-2.1mm power jack, built-in reverse connection protection for safe and stable power supply.
• Versatile physics experiment kit for classroom teaching, scientific research, electromagnetic study and DIY projects, fit for teachers, researchers and tech hobbyists.
