To answer the question "What happens to the magnetic field lines due to a current-carrying conductor when the current is reversed?", we can follow these steps: ### Step 1: Understand the Right-Hand Thumb Rule The Right-Hand Thumb Rule states that if you hold a current-carrying conductor with your right hand such that your thumb points in the direction of the current, then the direction in which your fingers curl around the conductor indicates the direction of the magnetic field lines. ### Step 2: Identify the Initial Direction of Current Assume we have a straight conductor with current flowing in an upward direction. According to the Right-Hand Thumb Rule, if the thumb points upwards (in the direction of the current), the fingers will curl around the wire in a specific direction, creating concentric circles of magnetic field lines around the conductor. ...
