Inducatnce - -x3BC-N2Arealength

The number of turns in an air core solenoid of length 25 cm and radius 4 cm is 100. Its self inductance will be5×10−4H5.4×10−3H2.5×10−4H2.5×10−3H

Inducatnce = μN2Arealength

The number of turns in an air core solenoid of length 25 cm and radius 4 cm is 100. Its self inductance will be
$5 \times 10^{- 4} H$
$5.4 \times 10^{- 3} H$
$2.5 \times 10^{- 4} H$
$2.5 \times 10^{- 3} H$

Inducatnce = $μ N^{2} \frac{A r e a}{l e n g t h}$
