How Do You Build An Electric Motor From Scratch?
Electric motors power everything from household appliances to the starters in cars, but the basic formula for building them is very simple. It centers around the notion of magnets pushing and pulling against each other, and the way in which that energy is transformed into electrical power. A simple electrical motor can be built from basic materials. Step 1 Wrap a length of enamel wire tightly around a thick pen, forming a circle. Leave about 2 inches of free wire on either end. Step 2 Slide the wire off of the pen. Wrap the free ends once or twice around the circle to hold it in place. There should still be a little bit of free wire at either end. Step 3 Sand the enamel off of one of the free ends of the wire using a piece of sandpaper. Then carefully lay the other free end flat on a tabletop and sand away the top half of the enamel. The bottom half should still be intact. Step 4 Straighten out a pair of paper clips. Bend the ends to form a hook. Step 5 Strap the paper clips to either
