The magnetic flux density inside a long current-carrying solenoid depends on which pair of quantities?

Correct answer A. Number of turns per unit length and current

Explanation

Inside a long solenoid B = μ₀nI, where n is the number of turns per metre and I is the current. The field does not depend on the solenoid's cross-sectional area.
