### Step-by-Step Solution: 1. **Understanding the Solenoid**: A solenoid is a long coil of wire that generates a magnetic field when an electric current passes through it. The magnetic field produced by a solenoid resembles that of a bar magnet, with distinct north and south poles. 2. **Magnetic Field Lines**: Magnetic field lines are used to represent the strength and direction of a magnetic field. They emerge from the north pole and enter the south pole of a magnet. The density of these lines indicates the strength of the magnetic field; closer lines mean a stronger field. 3. **Behavior at the Ends of the Solenoid**: Near the ends of a current-carrying solenoid, the magnetic field lines exhibit specific behavior: - **Convergence at the South Pole**: Near the south pole of the solenoid, the magnetic field lines converge. This means that the lines are coming closer together, indicating a strong magnetic field in that region. ...
