Fun Physical Science Experiment Model Homemade DIY Generator Motor Material School Students Teaching

Features: 1. Happy and easy to learn. 2. Exercise your children practical ability. 3. Train your children observation capability,thinking and analytical skills. Instructions: 1.Left-hand rule: electromagnetism, the left hand placed in a magnetic field, so that the magnetic induction lines vertical penetration of the palm, palm facing the N pole (fork into the point out) referred four fingers point to the current direction, the direction of thumb is that a conductor direction of the force. 2.Simple principle: power conductor in a magnetic field magnet provided continuously driven by Ampere force, resulting in rotational movement. Changing the magnetic field direction and the direction of the battery, wires inversion occurs. Please note that: the battery does not incuded. Package Included: 1 x Wind Forming Experiment Kit
