Question

The magnetic field inside the solenoid are in the form of

• A. curved lines.
• B. circular lines.
• C. parallel straight lines.
• D. zig-zag lines.

Answer 1

The correct option is C

parallel straight lines.

Step 1: Solenoid

1. A solenoid is made up of numerous circular turns of an insulated copper wire wound in the form of a cylindrical tube.
2. Its length is quite large as compared to the diameter of the solenoid.

Step 2: Magnetic field inside the solenoid

1. Within the solenoid, the magnetic field lines are parallel straight lines.
2. Thus, the magnetic field within the solenoid is the same and uniform at all points.

Hence, option (c) is correct.
