Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): On changing the direction of flow of current through a straight conductor, the direction of a magnetic field around the conductor is reversed.
Reason (R): The direction of the magnetic field around a conductor can be given in accordance with the left hand thumb rule.
The correct answer is option C, which states that assertion (A) is true but reason (R) is false.
Explanation:
The assertion states that on changing the direction of flow of current through a straight conductor, the direction of the magnetic field around the conductor is reversed. This is indeed true. When a current flows through a straight conductor, a magnetic field is generated around it. The direction of the magnetic field can be determined using the right hand rule. If the thumb of the right hand points in the direction of the current, then the curled fingers of the right hand indicate the direction of the magnetic field.
However, the reason given for this assertion is that the direction of the magnetic field around a conductor can be given in accordance with the left hand thumb rule. This is incorrect. The left hand thumb rule is used to determine the direction of the force on a current-carrying conductor placed in a magnetic field, not the direction of the magnetic field itself.
The left hand thumb rule states that if the thumb of the left hand points in the direction of the current, then the curled fingers of the left hand indicate the direction of the force on the conductor. This rule is based on the fact that a current-carrying conductor experiences a force when placed in a magnetic field.
In conclusion, while the assertion is true as changing the direction of current does reverse the direction of the magnetic field around a straight conductor, the reason given is false. The left hand thumb rule is not used to determine the direction of the magnetic field, but rather the direction of the force on a current-carrying conductor.
Reason (R): The direction of the magnetic field around a conductor can be given in accordance with the left hand thumb rule.
The correct answer is option C, which states that assertion (A) is true but reason (R) is false.
