At time t = 0 magnetic field of 1000 Gauss is passing perpendicularly through the area defined by the closed loop shown in the figure. If the magnetic field reduces linearly to 500 Gauss, in the next 5s, then induced EMF in the loop is:
detailed solution
Correct option is B
Area of given loop = A= 16×4-212×4×2 = 56 cm2 Induced emf, ε=dϕdt=1000−500×10−4×56×10-45 =56 μVTalk to our academic expert!
