PURPOSE: electromagnetic induction rule learning device is provided to improve interest of the creativity by exciting student. ;CONSTITUTION: the propylene acid tube solenoid that multiple coils (3,8) are wrapped in exterior clear curls up in the clockwise direction with coil (2,7) in multiple winding meters clockwise directions. A kind of both ends that LED (6) is connected to multiple coils, which are wound, to be rotated clockwise. A kind of both ends of LED (4) are connected, the coil, these winding counter clockwise directions. The pipe of the covering clear acrylic outer diameter of one lid (1) sizing material. A kind of permanent magnetism (5) change magnetic field connects electric power around coil and is shaking solenoid up and down. ;The 2013 of copyright KIPO submissions
