To find the magnetic moment of the coils in each case, we will follow these steps: ### Step 1: Determine the Current (I) in the Coil The current flowing through the coil can be calculated using Ohm's law: \[ I = \frac{V_0}{R} \] where \( V_0 \) is the voltage of the source and \( R \) is the resistance of the wire. ### Step 2: Find the Number of Turns (N) ...
