Direction of Current in a Horizontal Conductor:
When a straight conductor is held horizontally along the east-west direction, and the magnetic field lines associated with it are in an anticlockwise direction, the direction of current through the conductor can be determined using the right-hand thumb rule.
- Right-Hand Thumb Rule: According to this rule, if the thumb of the right hand points in the direction of the current, the curled fingers will indicate the direction of the magnetic field lines.
To determine the direction of current, we can use the right-hand thumb rule as follows:
1. Hold your right hand with the thumb pointing towards the east (in the direction of the conductor).
2. Curl your fingers in the anticlockwise direction.
3. The direction in which your fingers curl represents the direction of the magnetic field lines.
4. Therefore, the current through the conductor should flow in the opposite direction to the curl of your fingers, which would be from west to east.
Direction of Current in a Vertical Conductor:
When a straight conductor is held vertically and the current flows from north to south, the direction of the magnetic field lines can be determined using the right-hand grip rule.
- Right-Hand Grip Rule: According to this rule, if you hold a conductor in your right hand with your thumb pointing in the direction of the current, the fingers will indicate the direction of the magnetic field lines.
To determine the direction of magnetic field lines, we can use the right-hand grip rule as follows:
1. Hold your right hand with the thumb pointing downwards (in the direction of the current flow, from north to south).
2. The curled fingers will indicate the direction of the magnetic field lines.
3. Therefore, the magnetic field lines will be in a clockwise direction around the conductor when viewed from the top.
