9 a conducting loop of area a 9 cm2 and resistance r 160 q lies at rig
Question
9) A conducting loop of area A = 9 cm² and resistance R = 160 Q lies at right angles to a spatially uniform magnetic field. At time t =
0, the magnetic field and loop current are both zero. Subsequently, the current increases according to I = bt², where b = 0.4 A/s²?.What is the magnetic field strength at the time t = 0.8 s?
