Making your own transformer

Making your own transformer
So, basically a trans former is an arrangement of 2coils wound around a core which either steps up or reduces down the voltage(alternating). The principle of transformer is mutual inductance that if change in flux in a coil induces a change in flux of another coil then the coils are said to be coupled.and this phenomenon is called mutual inductance.
Materials

Iron core , 27SWG wire, 30 SWG wire, insulation like teflon tape
Procedure
1. Take the core and wrap it first with teflon tape completely.
2.take the 30SWG wire and wind it on the core, evenly.
3. Now take the 27 SWG wire and wind it with comparatively lesser turns.
Testing
Once you are all done you can just connect it to the city power supply and test it with the help of a multimeter.you can choose any wire as input wire according to your need for a step up or step down transformer.
Precautions
1 A.C. is really dangerous, handle all the things with care.
2. If there is a problem that the wires are burning then you can take a thicker wire.


That's all. Hope you liked it and tried it yourself.
