One hundred turns of insulated copper wire are wrapped around an iron core of cross-sectional area 0.100 m2. The circuit is completed by connecting the coil to a 100-%uF057 resistor. As the magnetic field along the coil axis changes from 1.00 T in one direction to 1.00 T in the other direction in 0.15 s, the average current in amperes that flows through the resistor is:
