Certain experiments must be performed in the absence of anymagnetic fields. Suppose such an experiment is located at thecenter of a large solenoid oriented so that a currentof I = 2.20 A produces a magneticfield that exactly cancelsEarth's 3.70 ✕ 10−5 T magneticfield. Find the solenoid's number of turns per meter.
