Given,
r = 0.02 m ; n = 11 turns ; I = 4 A ; v = 4.4 m/s ; x = 0.18 m
a)We know that,
B = u0 I/2 pi r
B = u0 I v/2 pi x^2
B = 2 x 10^-7 x 4 x 4.4/0.18^2 = 1.086 x 10^-4 T/s
Hence, B = 1.086 x 10^-4 T/s
b)We know that
emf = N d(phi)/dt = N A dB/dt
emf = 11 x 1.086 x 10^-4 x 3.14 x 0.02^2 = 1.501 x 10^-6 V
Hence, V = 1.501 x 10^-6 Volts
c)The change in field will be out of the page
d)counter clockwise
e)This is because the induced field will always appose the change due to which it is produced.
