PASSAGE
Two air-core solenoids are compared. Solenoid 1 has 600600 turns over a length of 0.30 m0.30\,\text{m} and carries 0.40 A0.40\,\text{A}. Solenoid 2 has 900900 turns over 0.45 m0.45\,\text{m} and carries 0.30 A0.30\,\text{A}. Viewed from the same end, the current around solenoid 2 is opposite to the current around solenoid 1. For a long solenoid, B=μ0(N/L)IB=μ_0(N/L)I.
How does the magnetic field inside solenoid 2 compare with that inside solenoid 1?
