28.7 The magnetic field of 60 cm long solenoid increases by 0.075 T when the current increases by 10.7 A. What is the number of turns in the solenoid?
here,
the magnetic feild increase , dB = 0.075 T
length , l = 60 cm = 0.6 m
let the number of turns in the solenoid be N
curret , dI = 10.7 A
dB = u0 * N * dI /l
0.075 = 1.26 * 10^-6 * N * 10.7 /(0.6)
solving for N
N = 3.34 * 10^3 turns
the number of turns in the solenoid is 3.34 * 10^3 turns
