How to make a simple generator

) Horseshoe magnet

(2) Cork (about 7 cm or 10 cm long)

(3) Plastic knitting needle

< p>(4) Fine wires

(5) 6 volt battery

(6) Wooden base (approximately 10 cm x 30 cm)

(7 ) 2 metal wire Strips (about 12 cm × 2 cm)

(8) 2 rubber strips, flat head nails

(9) 2 screws, pliers

(10) Hammer and Nails

Use a hammer and nails to drill 4 nail holes in both ends of each metal strip, about 0.5 inches from the end. Snap one end of each metal strip at an angle about an inch from the head. These will be the feet of each support.

Use two screws to secure the metal strip to the base. The two metal bars must be in a certain position so that the plastic knitting needle can pass through the two holes on the metal bars, as shown in Figure 4. The needle must protrude about 1 inch outside each trou support. The needle should be able to move freely back and forth in its holder, and the cork should be able to rest easily between the two poles of the horseshoe magnet. Insert the needle into a hole in the holder and push it through the wood from the end. to finish. The center of the sheet.

Wrap the wire around the cap about 50 times to form a spool as shown in the picture. Leave about 3 inches of wire on each end. At the ends of the wires, peel off about ½ inch of insulation and use tape to secure the two wires to opposite positions on the pins. Do not let bare wires touch each other or put tape on them.

The stripped wire is used to connect the other two battery wires. Press two thumbtacks in two slightly spaced locations under the bare wire. Peel about 1.2 cm of insulation from one end of the other wire, bend the wire and secure the elbow under the thumbtack withc the stripped end of the wire on top. With the stripped end of the thread above the height of the needle and tight against it, do the same with the other thread and secure it under another thumbtack so that the stripped end of the thread is on the other side of the needle. The distance between the two bare threads should almost touch the needle (when both needle threads are in the up and down position). Attach the horseshoe magnet to the board so that the coil is tight in the horseshoe socket of the magnet. Remove some of the insulation from the remaining ends of the wires and connect them to the battery. Pull and turn the spool with your hands and the motor will spin on its own. This experiment may not work the first time, so keep adjusting your engine setup.
