Generator
An electric generator or dynamo is a device for producing electricity that transforms kinetic or mechanical energy into electrical energy, in the presence of a magnetic field. In its infancy, it produced a direct current. With the development of research, scientists were able to develop it to produce an alternating current. In this, the hypothesis on the need to use permanent magnets was refuted. Generators in shape and size, including small and large, according to their purpose and use.
Its mechanism of action: the creation of an electromagnetic induction current through the approach of a magnetic field from a closed circuit (a wire coil), or the approach of a wire from a magnetic field. Moving away from the magnetic field from the center of the circle, and to move the wire or magnet we need mechanical energy, which is the rotating energy of the wire or renewable energy such as wind and water.
Generator industry
An electric generator can be produced using simple raw materials at home.
raw materials
- Small plank.
- Glue.
- XNUMX CDs.
- A good magnet separates to be in the shape of a disc with a diameter of 2 cm.
- sewing machine shuttle.
- Five small colored light bulbs.
- A roll of thin copper wire.
- Nail or screw 10 cm long.
- A toothpaste cap is attached to the center of the CD.
- Two nuts with a diameter of 2 cm.
Setting method
- Install the screw or nail in the middle of the plank.
- Glue one of the CDs to the wooden board using glue.
- Allow the disc to dry and stick to the board, for five minutes.
- During that, we make five loops of wire, by wrapping the wire on a suitable plastic box that can be used as a medicine box, and we wrap the wire around it about 25 times, when it is finished, we pull the ring out of the plastic box and cut the tip of the wire, the two free ends in each loop, which we tie until the loop holds together And after tying the ends, we clip them together with a small light bulb.
- We stick the wire loops on the first disc installed on the wooden plank, after putting a little glue, and estimating the distances between them so that they are consistent.
- We stick the shuttle in the middle of the disc, and above the shuttle we stick a nut.
- On the second disk, we stick the magnets on the poles of the disk, each magnet is 90 degrees away from the other.
- Stick the toothpaste cap in the middle of the second disc, but on the opposite side of where the magnets are attached.
- We stick a nut on the opposite side of the cover, i.e. in the direction where the magnets are located.
- We put the second disk on top of the first. The magnets should be towards the wires
- When turning the upper disk by hand, we notice the lighting of the lamps, and this is a result of the generation of an electric current in the coils of wires.
