Match List I with List II and select the correct answer using the code given below the lists: List I (Rule/Phenomenon) | List II…

The correct Answer is

A-1, B-2, C-3, D-4

Explanation

This question pertains to fundamental principles of electromagnetism, specifically rules and characteristics associated with magnetic fields generated by electric currents and forces experienced by current-carrying conductors in magnetic fields.

Statement-wise Analysis

1. A. Right-hand thumb rule - 1. Direction of magnetic field associated with a current-carrying conductor
   Correct: The Right-hand thumb rule (also known as Maxwell's corkscrew rule) provides a simple way to determine the direction of the magnetic field lines around a current-carrying straight conductor. If the thumb points in the direction of the current, the curled fingers indicate the direction of the magnetic field lines.
2. B. Fleming’s left-hand rule - 2. Direction of force on a current-carrying conductor in a magnetic field
   Correct: Fleming's left-hand rule is used to determine the direction of the force experienced by a current-carrying conductor placed in an external magnetic field. The thumb, forefinger, and middle finger of the left hand are held mutually perpendicular. The forefinger points in the direction of the magnetic field, the middle finger points in the direction of the current, and the thumb indicates the direction of the force.
3. C. Magnetic field due to straight conductor - 3. Concentric circles centered on the wire
   Correct: The magnetic field lines produced by a straight current-carrying conductor are concentric circles, with their centers lying on the wire. The direction of these circles is given by the Right-hand thumb rule.
4. D. Magnetic field inside a solenoid - 4. Uniform and parallel field lines
   Correct: Inside a long solenoid, the magnetic field lines are nearly parallel to each other and to the axis of the solenoid. This indicates that the magnetic field is uniform and strong within the solenoid. Outside the solenoid, the field is weak and non-uniform.

Key Takeaway

The Right-hand thumb rule determines the direction of the magnetic field around a current, Fleming's left-hand rule determines the direction of force on a current-carrying conductor in a magnetic field, the magnetic field lines around a straight conductor are concentric circles, and the magnetic field inside a solenoid is uniform and parallel.
