A 100.0-m-long, 1.20-mm-diameter copper wire (resistivity 1.70*1082m) is shaped into a circular coil that consists of 150 identical turns. The coil is then connected to the terminals of a 9.00-V-battery that has internal resistance of 1.50 12. Calculate the strength of the magnetic field (due to the current running through the coil) at the center of the coil.
