DC Feedback Motor explanation.

Подробнее о видео

Built a simple DC Feedback motor using:

1. 28-gauge enamel copper wire (180 turns)
2. Plastic bobbin
3. Neodymium (NdFeB) magnets (2 pieces, Grade 52)
4. Reed switch
5. Metal contact (for reed switch)

Motor Operation:

1. 1.5V battery powers the coil.
2. Coil generates a North pole on the front side.
3. Neodymium magnets are repelled by the coil's North pole.
4. Magnets move away from the coil.
5. Reed switch triggers when magnets approach.
6. Coil energizes, repelling magnets again.

Principles:

1. Electromagnetism: Current through the coil generates a magnetic field.
2. Magnetic repulsion: Like poles (North-North) repel each other.
3. Feedback mechanism: Reed switch controls coil energization.
