JEE Main 2020 Physics question
A uniform magnetic field B exists in a direction perpendicular to the plane of a square loop made of a metal wire. The wire has a diameter of 4 mm and a total length of 30 cm. The magnetic field changes with time at a steady rate dB/dt = 0.032 . The induced current in the loop is close to (Resistivity of the metal wire is m)
Answer: (C)
