Explanation / Answer

here,

radius , r = 0.475 m

number of turns , N = 300 turns

t = 4.11 ms = 0.00411 s

let the magnetic feild strength be B

V = dphi /dT

10000 = N * pi * r^2 * B /0.00411

10000 = 300 * pi * 0.475^2 * B /0.00411

solving for B

B= 0.19 T

the magnetic feild strength is 0.19 T
