MAKING A GENERATOR

TITLE: HOW TO MAKE HOMEMADE GENERATOR?

Contain:

Step 1

Find a 35mm plastic film can and remove the lid. Cut out two cardboard circles about 50mm diameter and cut out their centres (33mm diameter hole) so that they fit snugly onto the canister. Space the two circles about 1cm either side of the center of the can. Wind on a few turns of insulation tape on to the can, either side of the cardboard to hold them in place.

Step 2

Use the cardboard circles as a bobbin (or former) on which to wind the coil. Wind on 500 to 1000 turns of thin, insulated copper wire. Add a layer of sellotape to keep them from un-winding. Remember to leave about 10cm or so of wire free at each end.

Step 3

Scrape off some of the insulation (say 5mm or so) from the ends of the wire (using sandpaper) and connect to the LED (it does not matter which way round). Solder the connections if possible. Use some sellotape to secure the wire and LED to the bottom of the can.

Step 4

Pop a small (but powerful) magnet into the can and snap the lid back on. Hold the can between thumb and forefinger at the two ends of the can (with thumb or forefinger on the lid to stop it coming off !) and shake. The LED will light !!

Conclusion: The experiment is one of the example that we can make by our self. Please have try it at home!
