Introduction: DC Motor Brushed Style
What is it?
This is a very simple motor design that illustrates the right hand rule and the interaction between magnetic fields and flowing electric current. This interaction creates an effect where two sides of a rectangle of wire are pushed in opposite directions, thus making the rectangle spin. To learn more about the theory watch the video above.
3-6 Small circular neodymium magnets
1 AA Battery
1.5 meters 0.5mm laminated copper wire
2 50mm paper clips
50cm of insulation tape
1 Coin or button for stabilization
Step 1: Create Your Motor Coil
Step 1: Wrap wire around a rectangular object
Step 2: Tie of the ends in a way that wires are sticking out the sides as an axis for the coil to spin on
Step 3: Strip the ends of the wires (ONE FACE ONLY)
Step 2: Wrap the Battery to a Coin to Create a Stable Base
Step 3: Bend Paper Clips to Right Shape
Step 1: Bend the clips into an S shape
Step 2: Fold the top of each clip into a U shape
Step 4: Tape the Bend Cips to the Side of Battery
Step 1: Use about 10 cm of tape to attach each paper clip
Step 2: Wrap several turns of tape around the battery
Step 5: Place the Magnet and the Coil
Step 1: Place the magnet on the middle of the battery
Step 2: Place the coil on the clips and adjust untill it spins
To see the motor in action, watch the video from 9:45

This reminds me of some of my old intro to physics classes a few years back.

Except that I teach this to a group of gifted Year 3's and 4's.... I honestly think that at least half of them get it!
