A conducting loop with area 011 m2 and resistance 50 omega

Question

A conducting loop with area 0.11 m² and resistance 5.0 Ω lies in the x-y plane. A spatially uniform magnetic field points in the z direction. The field varies with time according to Bz=at²-b, where a = 2.6 T/s² and b = 8.8 T .

PART A

Find the loop current when t = 1.3 s .

Part B

Find the loop current when Bz=0.
