... Example 19.3: A solenoid 20 cm long and 40 mm in diameter with an air core is wound with a total of 200 turns of wire. The solenoid is to be used to exactly cancel the Earth's magnetic field where it is 3.0x10-5 T in magnitude. What should the current in the solenoid be for its field to exactly can ...
