Explanation / Answer
Given that the length ofconductor is L = 50 cm = 0.5 m Number of turns is N =500 The current inthe solenoid is I = 10000A ------------------------------------------------------------------------------------------- Magneticfield inside the solenoid is B = 0*N*I / L = (4 *10-7 T.m/A)(500)(10000A) / 0.5m = 12.56T
