A square single loop of wire 4.00 cm on a side with 875 turns lies in the xy-plane. The loop is in a uniform magnetic field that changes at a steady rate from B⃗ =(0.200T)i^+(0.150T)k^B→=(0.200T)i^+(0.150T)k^ at t = 0 to B⃗ =(0.300T)i^+(−0.200T)k^ B→=(0.300T)i^+(−0.200T)k^ at t=3.00s. At the time t=2.00s, a) find the magnitude of the induced emf in the coil. b) Find the direction of the induced current in the coil as seen from a point on the +z-axis.
