To find the number of turns per centimeter of the solenoid, we can follow these steps: ### Step 1: Understand the relationship between magnetic intensity (H), number of turns per unit length (n), and current (I). The magnetic intensity (H) in a solenoid is given by the formula: \[ H = n \cdot I \] where: - \( H \) is the magnetic intensity in A/m, - \( n \) is the number of turns per meter, ...
