Oaky, I've done the test.
Wound both with 20 turns.
#1Tx is the rough looking Hefei ECU-Tamura
CSArea of 37.1 sq/cm
16.47V RMS gives a result of 1 Tesla on the calculator.
.8235V/Turn
Fed winding with 16.47V RMS and showed reading of .47A
Am I correct in saying that VA = 7.74 ?
#2Tx is the much better looking Eaglerise Electric toroid
CSArea of 35 sq/cm
15.54V RMS gives a result of 1 Tesla on the calculator.
.777V/Turn
Fed winding with 15.54V RMS and showed reading of .36A
VA = 5.59
