Physics · Electromagnetic Induction
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 of dB/dt = 0.032 T/s. The induced current in the loop is close to (Resistivity of the metal wire is 1.23 × 10-8 Ω·m):
