Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 3.
The pattern of the magnetic field in the solenoid is shown below:
- The solenoid's one end acts as a magnetic north pole, while the other acts as a magnetic south pole. Within the solenoid, the field lines are in the form of parallel straight lines.
- It means that the magnetic field within the solenoid is the same at all points. That is, the field within the solenoid is uniform.
- The magnetic field lines are circular outside a solenoid because the magnetic field loops around the solenoid's coils, creating a circular pattern.
- Inside the solenoid, the magnetic field lines are straight because the magnetic field is uniform and parallel to the axis of the solenoid due to the alignment of the individual magnetic fields created by the current flowing through the coils. This results in a straight and uniform magnetic field inside the solenoid.
