My Motor

My motor uses an electromagnet made by running an electric current through a coil. I used 16 awg single-strand wire. I wrapped this around the base of two steel L brackets five times. Then I took a rod and cut off some of the end to use as the armature. I then tape the armature to make it even and I start to wrap 24 awg magnet wire around it. This creates another electromagnet and I did this by leaving a little bit of wire to start and I wrap down and back and then I cross over and I go down ad back until I come back to where I started. Farther down the rod, there is a cork with copper plating taped to it and the copper plating has a little bit of space between it. Rubbing up against the copper plating are 16 awg multi-strand wire used as brushes. The circuit is started with one end of the electromagnet attatched to one end of the battery, it goes through the electromagnet, which then leads to a switch (nice little touch, right?), then that leads to one of the brushes. The circuit later continues with the other brush leading to the other end of the battery. For the brushes, I made a makeshift "bridge" over the cork/copper and I drilled holes into them. Then, I tucked the brushes through the hole and make it touch the copper plating.
