A square loop of side 12 cm and resistance 0.60$\Omega$ is placed vertically in the east-west plane. A uniform magnetic field of 0.1 T is setup across the plane in north-east direction. The magnetic field is decreased to zero in 0.6 s at a steady rate. The magnitude of current during this time interval is

  1. $1.42 \times 10^{-3} A$
  2. $2.67 \times 10^{-3} A$
  3. $3.41\times 10^{-3} A$
  4. $4.21 \times 10^{-3} A$
