In this instrument a fiber post is viewed as which is covered by iron sheet on its 2/3 part. Fiber end of the shaft is free and Iron covered end is associated with a spring component which because of which post goes to its unique position. Additionally a fiber bobbin is utilized on which winding is wrapped. A stock of 230V A.C is applied across the twisting, bringing about attractive field inside the bobbin. Because of this attractive field N-S pair is made. Because of AC excitation iron concealed segment of the post going about as electromagnet and the contrary polarities for example S-N are made on it. As per attractive property inverse polarities draws in one another.
