This is a cool science project. We can relax with cool air from fan running out of a dc battery.
Step 1: Materials Required
1. A Dc motor
2. A propellor
3. A 9 Volt dc battery
4. A Switch
5. Soldering equipments
Step 2: Procedure:
1. Solder two wires to the dc motor.
2. Connect propellor to the motor.
3. Connect battery cap to the battery.
4.Connect the wires of motor , battery , switch as shown in the below circuit.
5.Then on the switch and enjoy.
Step 3: Conclusion
Battery is a current source. When we connect the terminals of the battery to switch then to motor, the electrons from the battery will flow through wires and switch then in the motor , due to electromagnetic induction , the rotor rotates. When we attach a propellor, it helps in moving the air molecules.
