A conducting wire of 100 turns is wound over and near the centre of a solenoid of 100 cm length and 2 cm radius having 600 turns. Calculate mutual inductance of two coils. |

Answer» Here, `N_(2) = 100, l = 100 cm = 1 m`, `r = 2 cm = 2 xx 10^(2) m, N_(1) = 600 , M = ?` `M = (mu_(0) N_(1) N_(2) A)/(l) = (mu_(0) N_(1) N_(2) pi r^(2))/(l)` `= (4 pi xx 10^(-7) xx 600 xx 100 xx 3.14 (2 xx 10^(2))^(2))/(1)` `M = 9.47 xx 10^(-5) H` |
