Two coaxial solenoids are made by winding thin insulated wire over a pipe of cross-section area A = 10cm^2 and length l = 20 cm. If one of the solenoids has 300 turns and the other 400 turns, their mutual inductance is ....... [mu_0=4pixx10^(-7) "TmA"^(-1)] |

Answer» `2.4pixx10^(-4)` H `M=(mu_0 N_1N_2A)/l` `=(4pixx10^(-7)xx300xx400xx10xx10^(-4))/0.2` `=24000000 PI xx 10^(-11)` `THEREFORE M=2.4 pixx10^(-4)` H |
