Answer #1

L, be the self inductance of solenoid of radius r 3.0cm and number of tunrs N length of the solenoid-L-7.5cm ㄫㄨ N number of turns L-Length of solenoid- 7.5cm A area of cross section πί- 0.0028274 m substituting all the know values gives 634 0 ΔΙ change in current 2.5 A / s At induced voltage = ε di dt -19.0e - 03Hx2.5 =10.0475 V
