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.

Components:

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

Sand paper

Tools:

Scissors

Wire cutters

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
