Explanation / Answer

a) induced emf  = d phi / d t

= S * dB / dt = pi * 0.1452 * 0.5 = 0.033 V

induced current I = E / R

= 0.033 / 0.21

induced current = 0.157 A = 157 mA

b) loop current direction is clockwise

c) induced emf  = d phi / d t

= S * dB / dt = pi * 0.1452 * 0.5 = 0.033 V

induced current I = E / R = 0.033 / 0.21

induced current = 0.157 A = 157 mA

d) loop current direction is clockwise

e) There is no induce emf

I = 0 A

f) There is no induced current
