Step 1: Understanding the Magnetic Field in a Solenoid:
A solenoid is a long wire wound into a coil. When current flows through the solenoid, it produces a magnetic field. This field has distinct patterns both inside and outside the solenoid.
Step 2: Magnetic Field Inside the Solenoid:
Inside the solenoid, the magnetic field lines are straight, parallel, and closely packed. This indicates that the magnetic field is strong and uniform. The uniformity of the field is a result of the additive effect of the individual magnetic fields created by each loop of wire in the solenoid.
Step 3: Magnetic Field Outside the Solenoid:
Outside the solenoid, the magnetic field lines curve back around and form loops. These curved lines resemble the field pattern around a bar magnet, where the magnetic lines of force extend from one pole of the magnet to the other.
Step 4: Field Pattern Explanation:
- Inside the solenoid: The field is uniform, represented by straight, parallel lines.
- Outside the solenoid: The field forms a loop, similar to the field around a bar magnet.
Step 5: Correct Diagram:
The correct diagram would show parallel lines inside the solenoid, indicating the uniform field, and curved lines outside the solenoid, demonstrating the looping field pattern. This type of field pattern is characteristic of a solenoid when current flows through it.
