Motor Blog Reflection

In this current unit the focus of the class is to understand magnetic fields. In this particular section we are encouraged to learn using hands on activities which will later help us in making wind turbines. This section we have created a motor, in which all of its parts functions are vital to the motor actually working. While in this case we have no use for this motor to run things, it was a great learning experience. 

The main parts of the motor include a battery, 2 paper clips, coil, and a magnet. Like my group, some groups chose to use electrical tape to keep the paper clips attached to the battery itself and others, still, chose to use wood and rubber bands to stabilize their motors. The battery is used as a power source to move mechanical energy.The 2 paper clips are used to help carry a current through the battery, which also lead to both ends of the coil.The magnet provides a magnetic field in the motor.The coil is the main part of the motor. The coil is the conductor. The conductor is based off of how many turns in the coil there are and if the coil surrounds an iron core.


We scraped the armature of the coil a certain way because it determines the way the motor spins. If both sides of the coil were completely scraped, the motor would just swing back and forth, rather than making a complete rotation. We strip only one side of the coil and the entire other side of the coil, so that the motor will continue to rotate instead of swinging back and forth which it wants to do. By stripping the armature we have enabled the coil to rotate one way and then let the momentum rotate it back to the top so then energy is put back in and the same thing occurs.


The magnetic field which puts a torque on the coil. The current in the wire create another magnetic field because of the moving charges. The direction of the force is determined by which side of the coil has been fully stripped.
