In the Right-Hand Thumb Rule, the thumb is directed towards the direction of:

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. current.

In the Right-Hand Thumb Rule, the thumb points in the direction of the current flowing through a straight conductor. The curled fingers then represent the circular magnetic field lines around the conductor.

Key Applications:

  1. Straight current-carrying wire: Thumb = current, fingers = magnetic field direction.

  2. Solenoid/coil: Thumb = north pole of the magnetic field; fingers = current flow direction.

Other options:

  • Electric field: Irrelevant to this rule.

  • Motion of conductor: Related to Fleming’s Left-Hand Rule (motor principle).

  • Magnetic field: Represented by fingers, not thumb.
