Certain experiments must be performed in the absence of any magnetic fields. Suppose such an experiment is located at the center of a large solenoid oriented so that a current of I = 2.70 A produces a magnetic field that exactly cancels Earth's 3.70 ✕ 10−5 T magnetic field. Find the solenoid's number of turns per meter.
