Como fazer um MOTOR elétrico com um ÍMÃ (EXPERIÊNCIA de FÍSICA)
How to Make a Homemade Electric Motor
In this video, the process of creating a homemade electric motor using simple materials is demonstrated.
Creating the Coil and Base
- Start by making a coil using copper wire and a large battery, wrapping the wire around the battery about ten times.
- Secure the coil by tying one end and stripping off the varnish from one side for electrical conductivity.
- Prepare a base by cutting a balloon ring to fit around the battery, securing it with rubber bands, and attaching safety pins as positive and negative terminals.
Assembling the Motor
- Attach a magnet to complete the base setup.
- Connect the coil ends to safety pins, creating an electric circuit that interacts with the magnet to induce motion.
Understanding How the Electric Motor Works
This section delves into explaining how the homemade electric motor functions based on electromagnetic principles.
Working Principle of the Motor
- The coil acts as an electromagnet when electricity flows through it, interacting with a fixed magnet underneath.
- The interaction causes rotational movement as the coil seeks alignment with the magnet due to magnetic attraction and repulsion cycles.
Optimization Tips
- Experiment with varying coil turns and magnet positions for optimal motor performance.
- Emphasizes adjusting these factors for better understanding and efficiency in building similar projects.
