Electromagnetic Science Electromagnetic Ball Ejection Acceleration Inertia Ball Physics Teaching Aids

Features

• An experimental teaching aid that realizes reciprocating rolling by electromagnetically changing the movement direction of the steel ball and rolling it back and forth.
• After receiving the product, tear off the protective film on the support plate, otherwise it will not be easy to tear off after a long time.
• Find the built-in steel balls, place them on the track, and move the steel balls by hand to test the concentricity of the track to prevent beads from falling out.
• Plug in the power. If the indicator lights of the coils at both ends are red, it means the operation is normal. Let the steel ball slide into the coil at one end, the blue light will flash, and the steel ball will automatically move to the other end, and so on.
