i.
Measurement
on cross sectional area of wires.
This analysis is to determine and compare the two
different types of AWG wires. One is 23 AWG and the other is 20 AWG.

Comparison of 20 AWG
and 23 AWG
a) The result below shows the comparison
between using the fixed diameter of turns and number of turns.
When Transmitter size=18N,10cm and
Receiver diameter of turns is fixed, d =9cm
