According to the right-hand thumb rule, the right hand's outstretched thumb points in the direction of?

According to the right-hand thumb rule, the outstretched thumb of your right hand points in the direction of the current or the motion of the conductor. The curled fingers of the hand indicate the direction of the magnetic field lines around the conductor.

Explanation:

The right-hand thumb rule is used to determine the direction of the magnetic field produced by a current-carrying conductor.

• Thumb: Represents the direction of the electric current.
• Fingers: Represent the direction of the magnetic field, which forms concentric circles around the conductor.

This rule is a simple way to visualize the relationship between current and the magnetic field in electromagnetism.
