Generators refer to mechanical equipment that converts other forms of energy into electrical energy. They are driven by a water turbine, steam turbine, diesel engine or other electrical machines and generate electricity from water flow, air flow and fuel. nuclear combustion or fission. The energy is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy.
The first step? Make a coil
Wrap the highlighter with enameled wire for about 15 turns. Be careful not to wrap both ends of the wire, leaving both ends of the wire free. Then wrap both ends of the thread around the spool to secure the shape, as shown in the picture below
Note that this is a complete thread
Then use a utility knife to remove it. part of the insulation at both ends of the wire layer,as shown below. Note that a full turn of insulation can be removed from one end, but only half the insulation from the other end. In other words, when the coil is spinning, half the time there is no electricity.
The second step is to make the backing
In this step, place the bobbin on the two needles with larger pinholes. If such a needle is not available, wire or paper clips can be used instead as a thread backing.
The third step of assembly
Place the battery flat on the table and fix it with plasticine, as shown in the picture below.
Step 4: Attach the wire holder and magnet
Experimental principle
In this experiment, the coil, wire and battery form a circuit farm. A magnetic field is generated around the coil where the current flows, which repels the magnet underneath and turns it aroundner
