Hi everyone,
Is it possible to make inductors of desired values by just winding few turns of wire on a pencil.Basically the problem is that the inductors are not available in the city or anyother nearby.So whenever I want to make a college project or something like that,the circuit is never completed and it just stays on paper.
Some of my collegues told me that if you just wind few turns of wire on a pencil,and then take the pencil out of the coil I will get an inductor,whereas some told me that it not possible to make an inductor by just winding few turns and the circuit with these kinds of coils never work.
I am really confused and I need your expertise on this.Is there a formula relating type of wire,number of turns and the inductance in Henrys?
