How to Build an Electromagnetic Generator

A simple way to build an electromagnetic generator!

Supplies

Materials: cardboard, bottle cap, straw, propeller, motor, led light, glue

Tools: pencil, ruler, scissors, xacto knife, glue gun

Step 1: Draw Sides for the "windmill" on Cardboard

Make them all even, with smaller tops than bottoms. Use a ruler to help. Create and add your own cut outs!

Step 2: Cut Out Pieces

The xacto knife is helpful for the cut outs. Save a piece for the base!

Step 3: Create the Windmill Stand

Glue each piece to the base and to each other (I used hot glue). Make sure they are touching on all sides!

Step 4: Glue on the Top

Find a piece from the scraps that will fit on top of the stand. Shape it into a square and glue it on.

Step 5: Glue on Base for Light Stand

Any type of small plastic bottle cap will do.

Step 6: Gather Pieces for Light Stand

Look trough the scras from the cut outs. Create 4 identical pieces, along with one square piece.

Step 7: Glue Together the Stand

Using the glue gun, glue the short side of the pieces to the square. Make sure the sides of the pieces touch.

Step 8: Glue Light Stand On

Glue the light stand onto the top of the bottle cap, alonging room for the edge to hang over.

Step 9: Insert LED Light

Create a small hole in the center of the square backing. Insert the light into the whole, with the metal sticking out the back.

Step 10: Glue Straw Onto Motor

Cut a small piece of the straw off. Glue it to the axle of the motor, with extra hanging off.

Step 11: Add the Propellor

Glue the propellor to the opposite end of the straw.

Step 12: Glue the Motor on

Glue the large part of the motor to the cardboard, with the fan towards the front.

Step 13: Connect the Wires

Create a hook with the metal extending out of the wire. DO the same with the LED. Make hook each write a different leg of the LED. Make sure the legs do not touch.
