A solenoid of radius 1.0 mm with 720 turns and a length of 5.2 m surrounds a pigeon cage.
What current must be in the solenoid so that the solenoid field just cancels Earth's 4.2 × 10^-5 T magnetic field (used occasionally by the pigeons to determine the direction they travel)?
Express your answer with the appropriate units.
