FYP 2 (WEEK 8)

when number of turns is fixed to 12 and value of diameter of turns has varied to 4 values which are 7,9,10,12.

The graph when the number of turns =12 is fixed;


Figure shows graph on the Inductance VS Diameter of Turns. The number of turns has fixed to be 12 and the diameter of turns has varied to 4 values which are 7, 9, 10, 12. The values of inductance are getting increase as the diameter of turns increasing. The highest value of inductance is 6.147mH for 12cm diameter, and the lowest value of inductance is 3.244mH for 7cm diameter. The greater coil diameter presents less opposition to the formation of magnetic field flux for a given amount of field force (amp-turns).
