A 14-gauge wire has diameter of 1.6338 mm, and carries a current of I : 1.89 A. The wire is wound tightly around a wooden core, with neighbouring coils touching and not overlapping, so that that it produces a solenoid of length l m. if we now space out the wires so that the solenoid stretches to 1.17 m. what is the magnetic eld inside the solenoid? Give your answer to two decimals, in units of 103 tesla: B = mT
