Here is a picture of our battery powered motor. 
To make this motor, we used the following materials:

• Wooden block
• Batery
• Magnet
• Coiled Wire
• Paper clips
• Rubber band
• Electrical Tape

The battery supplies voltage and current
The coiled wire provides a pathway for current to flow.   The more turns in the wire, the greater the force is felt
The paper clips connects wire to battery, completes the circuit
The magnet creates a magnetic field, causing the moving electrons in the flowing current of the wire to move

Armature
In order to allow our motor to function correctly, we had to scrape off one side of the coil. We only scraped off one side because if we scraped all around, current would want to flow in both directions. We then attached the wire to the paper clip to allow the flow of current.

Why does the motor turn? 
The magnetic field is the reason the motor is able to function. The force of the magnet is charged by the battery which is perpendicular to the motor. This creates force. The magnet causes a magnetic field, therefore charges move in one direction, causing the motor to rotate. It is able to turn because the force is in one direction. Again, we scraped off the sides of one end of the coil, because if force was going in both directions, the motor would not be able to function.
