Solution

Q.
The magnetic intensity at the center of a long current carrying solenoid is found to be $1.6 \times 10^{3} {Am}^{- 1}$ . If the number of turns is 8 per cm, then the current flowing through the solenoid is ________ A. [2023]

Ans.
(2)

$H = \frac{B}{μ_{0}} = \frac{μ_{0} n i}{μ_{0}} = n i$

$i = \frac{H}{n} = \frac{1.6 \times 10^{3}}{(\frac{8}{10^{- 2}})} = 2 A$
