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 = 3.40 A produces a magnetic field that exactly cancels Earth's 4.50 x 10-5 T magnetic field. Find the solenoid's number of turns per meter. HINT turns/m
