Step 1: Understanding solenoid behavior.
A solenoid is a coil of wire, and when an electric current passes through it, it generates a magnetic field similar to that of a bar magnet, with distinct north and south poles.
Step 2: Magnetic field of a solenoid.
When current flows through the solenoid, the magnetic field created within the solenoid behaves like the magnetic field of a bar magnet. This means the solenoid has a defined north and south pole at opposite ends.
Step 3: Conclusion.
Thus, when current flows through a solenoid, it behaves like a bar magnet, with a clear north and south pole.
