A single circular current loop 18.0 cm in diameter carries a 2.40 A current.?
Suppose that we now connect 1150 of these loops in series within a 540 cm length to make a solenoid 540 cm long. What is the magnetic field at the center of this solenoid?
Is the magnetic field found in part B n = 1150 times the field at the center of the loop in part A? Why or why not?
